Answer:
Deoxyribonucleic acid is the macromolecule carries the genetic information. It has two phosphate sugar back bone chains which are joined together with the help of nucleotides (A, T, G, and C). This set of nucleotide refers as gene. These genes define the primary function of DNA to carry genetic information. This DNA structure gets coiled in manner that can carry large amount of information. These nucleotide sequences have ability to get transcribed into protein molecule with the help of translation and transcription factors.
One strand of sequence is sufficient to maintain coding sequence. The pair wise structure helps in case of one strand of structure get damaged and it required in process of replication.
Base stacking provides the stability in the structure of the DNA. The corresponding nucleotides combine with other molecule and minimize the hydrophobic effect. This molecule combines in the perpendicular alignment to the DNA base line.
It often found that TATA box on 5’ end. It is found that on 5’ because process starts from 5’ end and TATA box have A, T nucleotide. These molecules have double hydrogen bond, which is weaker then G, C pair.
Explanation:
The structure of DNA adapted to its function - DNA contains the instructions needed for an organism to develop, survive and reproduce.
DNA sequencesDNA has nucleotide made up of pentose sugar and phosphate backbone, and nitrogenous bases in a particular sequence.The sequence converted into messages that can be used to produce proteins, which are the complex molecules that do most of the work in our bodiesDNA winds into a double helix, with hydrogen bonding between the bases of each strand like the rungs of a ladder.The order of nucleotides in a gene dictate the amino acid sequence of the proteinDNA acts to store information while proteins are the effector molecules.
Thus, The structure of DNA adapted to its function - DNA contains the instructions needed for an organism to develop, survive and reproduce.

Suppose that a cytoplasmic protein (a protein that will function in the cytoplasm inside of the cell) is synthesized by a particular cell type. Describe the route that this protein will take from the moment its synthesis starts in the nucleus until it makes it into the cytoplasm.
Answer:
A specific gene that contains the information to encode the target protein is transcribed as a primary transcript (pre-mRNA). Subsequently, the pre-mRNA is processed to form a mature mRNA. Finally, this mRNA then moves through a nuclear pore from the nucleus to the cytoplasm where proteins are translated in the ribosomes
Explanation:
The cell nucleus contains the majority of the cell's genetic material localized on linear molecules called chromosomes. During transcription, genes (specific chromosome segments) are used to synthesize primary transcripts (pre-mRNAs) which are then proceeded to produce mature messenger RNAs (mRNAs). RNA processing involves the removal of non-coding intron regions and the joining of coding exon regions (RNA splicing) in order to form a mature mRNA sequence. Subsequently, the mature mRNA leaves the nucleus through the nuclear pores of the nuclear membrane and travels to the ribosomes where is decoded (translated) to produce a specific polypeptide chain (i.e., a protein). Within the ribosome, the mRNA strand binds to multiple transfer ribonucleic acids (tRNAs) via complementary and consecutive three-nucleotide mRNA sequences called triplets or codons, and tRNAs deliver specific amino acids that are consecutively added to the polypeptide chain.

O During fission, hydrogen is split apart into helium.
O U-235 is created from nuclear fusion reactions.
Exothermic reactions absorb heat and light.
The sun uses some of its own mass during fusion reactions.
C
Me To
Answer:
The sun uses some of its own mass during fusion reactions.
Explanation:
This is because the sun consist of hydrogen and helium. And the sun gravity compresses the gases hydrogen and helium and they become hot.
Heat and pressure forces hydrogen together to form helium which is nuvlear fusion.
Nuclear fusion is the combination to two nuclei or more nuclei to form one or more subatomic nuclear.

Answer:
In addition to lipids, membranes are loaded with proteins. In fact, proteins account for roughly half the mass of most cellular membranes. Many of these proteins are embedded into the membrane and stick out on both sides; these are called transmembrane proteins.The cell membrane contains a phospholipid bilayer, but the terms are not interchangeable.In addition to the phospholipids, the plasma membranes of animal cells contain glycolipids and cholesterol. ... Because the interior of the phospholipid bilayer is occupied byExplanation:

survive?
A. Inventing tools can help humans survive in their environment.
B. Overusing resources can make a survival practice unsustainable.
O .
C. Developing different religions can lead to conflict among
societies.
D. Having opposable thumbs helps humans grasp objects.
Answer : A
Explanation:
Inventing tools can help humans survive in their environment. Therefore, option (A) is correct.
Why inventing tools help human survive?Culture refers to the shared beliefs, values, practices, and knowledge that characterize a group or society. Humans have relied on culture to survive and thrive for thousands of years. Inventing tools is an example of how culture can help humans survive. By creating and using tools, humans are able to adapt to and manipulate their environment to meet their needs. For example, early humans used tools to hunt, gather food, and build shelters, which helped them survive in their environment.
Overusing resources can lead to unsustainability and environmental degradation, which can threaten human survival. Developing different religions can lead to conflict among societies and does not necessarily help humans survive. Having opposable thumbs is a physical adaptation that has helped humans develop complex motor skills, but it is not an example of how culture helps humans survive.

Answer:
Adenine (A) = 28%
Cytosine (C) = 22%
Explanation:
The DNA molecule, which is the genetic material that stores or holds information needed by the cell for growth, reproduction etc. Structurally, the DNA is composed of nucleotide subunits, which are of four types namely; Adenine, Guanine, Cytosine, and Thymine etc.
According to Chargaff in his complementary base pairing rule, he states that Adenine will always pair with Thymine (A-T) while Guanine will always pair with Cytosine (G-C). Based on this, Chargaff further stated that the amount of adenine must be equal with that of thymine while that of guanine must be equal to cytosine.
In total, their total amount must be equal to 1 or 100% i.e. (A + T) + (G + C) = 100%. In this question, 22% of Guanine are found in the DNA of a fox. This means that automatically, the percentage of cytosine is 22%. We then calculate the amount of Adenine and Thymine as follows:
(A + T) + (G + C) = 100%
A + T + 22 + 22 = 100
A + T + 44 = 100
A + T = 100 - 44
A + T = 56
Since A = T,
56/2 = 28
Hence, A = 28%, T = 28%

Explanation:
The following are internal cellular conditions :
A) temperature, pH, water concentration, salt concentration.
Temperature facilitates deciding what can input or depart the cellular and the way properly molecules observed inside the membrane can function. Temperatures that might be too excessive or too low can severely harm and, in the intense temperature ranges, kill the cellular via their impact at the cellular membrane.
Physiologically ordinary intracellular pH is maximum generally among 7.0 and 7.4, even though there may be variability among tissues (e.g., mammalian skeletal muscle has a tendency to have a pHi of 6.8–7.1). There is likewise a pH version throughout special organelles, that can span from round 4.5to 8.0.
Water concentration:
Water molecules flow into and out of the cell at an identical fee, so the length stays constant. then a cell. This method of water attention is better within the cell than outside. Thus, water flows out of them, inflicting them to shrivel or maybe die.
Salt concentration:
