translation is accomplished by the interaction of three main components which include mrna, trna, and _____________.

Answers

Translation is accomplished by the interaction of three main components which include mRNA, tRNA, and ribosomes.

Translation is the process of protein synthesis, which occurs in all living cells. This occurs when the genetic code, which is found in the form of DNA, is transcribed into mRNA (messenger RNA) and then translated into a protein. Translation is a complex process that occurs in multiple stages.Translation involves the following steps:Initiation: In this stage, the ribosome binds to the mRNA and scans it until it reaches the start codon, AUG. Once the ribosome reaches the start codon, the tRNA carrying the amino acid methionine (Met) binds to the start codon.Elongation: During this phase, the ribosome transfers Met-tRNA to the aminoacyl (A) site, forming a peptide bond between the carboxyl end of the polypeptide chain and the amino group of the incoming amino acid. The ribosome shifts to the next codon on the mRNA and a new aminoacyl tRNA is bound to the A site. The ribosome transfers the Met-tRNA to the P site and a new peptide bond is formed.Termination: During the last stage of translation, the ribosome reaches a stop codon, which signals the end of the protein-coding sequence. Release factors bind to the ribosome, causing it to release the mRNA and the polypeptide chain.

how do cancer cell differ from noncancerous cell? how are they similar ?

Answers

1) grow in the absence of signals telling them to grow.

2)
Normal cells follow a typical cycle: They grow, divide and die. Cancer cells, on the other hand, don't follow this cycle. Instead of dying, they multiply and continue to reproduce other abnormal cells. These cells can invade body parts, such as the breast, liver, lungs and pancreas
Answer:

Cancer cells differ from noncancerous cells in several ways. Here are a few examples:

1. Uncontrolled Growth: Cancer cells grow and divide uncontrollably, unlike normal cells, which have a regulated growth cycle.

2. Genetic Changes: Cancer cells have genetic changes or mutations that cause them to behave abnormally, which can lead to the formation of tumors.

3. Immortality: Cancer cells can divide indefinitely, unlike normal cells, which have a limited lifespan.
Invasion and Metastasis: Cancer cells have the ability to invade and metastasize to other parts of the body, while normal cells generally stay in one location.

However, cancer cells also share some similarities with normal cells. Both cancer cells and normal cells are made up of the same types of molecules, such as proteins, lipids, and nucleic acids. They also require nutrients and energy to survive and grow. Additionally, cancer cells can undergo many of the same processes as normal cells, such as DNA replication and cell division. However, these processes are dysregulated in cancer cells, leading to uncontrolled growth and other abnormalities.

Answers

d) Friedreich ataxia is a trinucleotide repeat disorder that is not consistent with the hairpin formation portion of this model. (GAA repeat).

The increase of a GAA trinucleotide repeat in the first intron of the frataxin (FXN) gene on chromosome 9 causes Friedreich ataxia. The expanded GAA repeat in this disorder causes the creation of a stable DNA hairpin structure.

Frataxin is a mitochondrial protein that is required for iron-sulfur cluster formation and oxidative phosphorylation. The trinucleotide repeat  sequence in the provided model is CGAA, which is inconsistent with the GAA repeat seen in Friedreich ataxia.

This model's hairpin formation component is also irrelevant to the pathogenesis of the other trinucleotide repeat disorders mentioned in the because their repeat sequences do not form stable hairpin structures.

Answers

The botanist, Dr. Flowers, would expect to see C6H12O6 and O2 as the end products of photosynthesis in the plants on Planet X. The correct option is (d).

Dr. Flowers, a botanist, is measuring the photosynthesis of local plants on Planet X. Her hypothesis is that the end products of photosynthesis in Planet X's plants will be the same as those of Earth's plants.

If Dr. Flowers' hypothesis is correct,  C6H12O6 and O2, would be anticipated from the plants on Planet X if Dr. Flowers' hypothesis that the end products of photosynthesis in Planet X's plants will be the same as those of Earth's plants is correct.

The primary output of photosynthesis is glucose or sugar (C6H12O6) and oxygen (O2). 6 CO2 + 6 H2O + light energy → C6H12O6 + 6 O2. This equation of photosynthesis shows that carbon dioxide (CO2) and water (H2O) are used in photosynthesis, whereas oxygen (O2) and glucose (C6H12O6) are released as products.

Therefore, Dr. Flowers' hypothesis is that Planet X's plants, like Earth's plants, will produce glucose and oxygen as photosynthesis end products. Hence, option D is correct.

in mitosis, the main difference between plant and animal cells is that

Answers

The main difference between plant and animal cells during mitosis is the process of cytokinesis. Animal cells undergo cytokinesis through the formation of a cleavage furrow, which is the constriction of the cell membrane at the equator of the cell, which eventually separates the two daughter cells.

The plant cells undergo cytokinesis through the formation of a cell plate. During telophase, the vesicles from the Golgi apparatus fuse at the centre of the dividing cell, forming a cell plate that gradually grows outward towards the cell walls, separating the two daughter cells.

Another difference between plant and animal cells during mitosis is that plant cells have a rigid cell wall that must be split during cytokinesis, while animal cells have a flexible cell membrane that can easily form a cleavage furrow. Additionally, plant cells have a unique organelle called the spindle pole body, which helps to organize the spindle fibres during mitosis.

which phase of hemostasis is vessel contractility most important during?

Answers

Vessel contractility is most important during the vascular phase of hemostasis. Because the vascular phase is the initial phase of hemostasis that occurs immediately after injury to a blood vessel.

Blood vessels are tubular structures that form a network throughout the body, transporting blood to and from the heart. There are three types of blood vessels: arteries, veins, and capillaries. Arteries carry oxygen-rich blood away from the heart to the rest of the body, while veins carry oxygen-poor blood back to the heart. Capillaries are small, thin vessels that connect arteries and veins, allowing for the exchange of nutrients, oxygen, and waste products between the blood and tissues.

The walls of blood vessels are composed of three layers: the inner layer or endothelium, the middle layer or smooth muscle, and the outer layer or connective tissue. These layers work together to regulate blood flow, maintain blood pressure, and provide structural support to the vessels.

The presence of pharyngeal gill slits in certain species of echinoderms that appear early in the fossil record would suggest that these structures are not unique to chordates and that they may have evolved independently in different lineages.

One of the distinguishing characteristics of chordates are pharyngeal gill slits, which are employed for breathing or filter feeding. It would imply that they perform a comparable purpose in these species if echinoderms, which are not chordates, also evolved these structures. This would strengthen the argument that evolution is a branching process rather than a linear path, with numerous independent adaptations taking place in various lineages throughout time.

It's crucial to remember that the existence of these features in early echinoderms does not necessarily mean that echinoderms and chordates have a direct evolutionary connection.

how are the lock and key and induced fit models different

Answers

The lock and key model is a theoretical illustration of how enzymes interact with substrate molecules while the induced fit model suggests that the enzyme changes its shape as it interacts with the substrate molecule. In this way, the two models are different.

The lock-and-key model of enzymes claims that the shape of the active site on the enzyme molecule is such that it specifically matches the shape of a complementary substrate molecule. According to this model, the active site is rigid and unchanging, and the substrate molecule's shape must fit into it precisely.

The induced fit theory suggests that as a substrate approaches the enzyme's active site, the active site's shape shifts slightly to accommodate the substrate's shape, resulting in a tighter, more snug fit. According to this theory, the active site and substrate molecule both shift as they interact, with the enzyme shifting into a new shape that is optimized for catalysis when bound to the substrate molecule.

C). Long-lasting proteins are likely to make the cell cancerous.
D). Cells lack the raw materials to make most of the proteins they need.
E). Most proteins are used only once.

Answers

The advantage of short-lived proteins is that they enable the cells to adjust (control) gene expression when this is critical to their well-being.  The correct option is B.

Proteins are biomolecules composed of one or more long chains of amino acid residues, which play a significant role in most biological processes. Amino acids are connected to each other in a linear chain through peptide bonds in a particular order defined by the genetic code. The sequence of amino acids in a protein defines the structure and functionality of the protein, allowing it to carry out a broad range of functions within the cell or organism. Proteins have many vital functions in the body, such as providing structure, acting as enzymes to catalyze chemical reactions, serving as signalling molecules, and performing various other metabolic, transport, and regulatory functions.Short-lived proteins, unlike long-lived proteins, are responsible for a variety of cellular functions, including the regulation of gene expression, rapid responses to environmental stimuli, and short-term metabolic adjustments, among others. As a result, they assist cells in adapting to their environment, maintaining homeostasis, and avoiding cellular dysfunction caused by the buildup of unwanted molecules.Long-lived proteins, on the other hand, may produce accumulated damage over time, leading to cellular and tissue impairment. Short-lived proteins are highly regulated, and their speedy elimination from the cell is critical for their proper function. Furthermore, short-lived proteins are degraded by the cell's intracellular proteolytic machinery, allowing the cell to quickly remove proteins that are no longer required or have become harmful. Thus, short-lived proteins play a critical role in maintaining cellular health and preventing disease. So, the answer to the given question is option B. Short-lived proteins enable the cells to adjust (control) gene expression when this is critical to their well-being.

The ear is the organ of hearing and equilibrium in vertebrates, in humans consisting of an external ear that gathers sound vibrations, the middle ear in which the vibration resonate against the tympanic membrane, a fluid-filled internal ear that maintains balance and that conducts the tympani vibrations to the auditory nerve, which transmits them as impulses to the brain. The Cochlea is a spiral-shaped cavity forming a division of the internal ear in humans and in most other mammals.
