Transcription, post-transcription, translation, and post-translation . DNA is keep within the nucleus of organism cells, wherever it'stranslated into mRNA.
The freshly created mRNA is then taken from the nucleus and placed within the protoplasm, wherever ribosomes convert it into supermolecule. The nuclear membrane physically separates the processes of transcription and translation; transcription solely takes place within the nucleus, and translation solely takes place outside the nucleus, within the protoplasm. At any purpose within the method, organic phenomenon isregulated.
Regulation might manifest itself at the epigenetic level, the transcriptional level, the post transcriptional level , the translational level or once the super molecule has been made(post-translational level).
Regulation might manifest itself at the epigenetic level (when DNA is uncurled and discharged from nucleosomes to bind transcription factors), the transcriptional level (when polymer is produced), the post-transcriptional level (when polymer is processed and exported to the cytoplasm), the interpretation level (when polymer is translated into protein), or the post-protein level (when the supermolecule has been produced) (post-translational level).

Name a product of cellular respiration that is used as a reactant in photosynthesis? (SC.912.L.18.9)
02
O ATP
Glucose
CO 2
Carbon dioxide is a product of cellular respiration that is used as a reactant in photosynthesis (option 4).
What are the processes of photosynthesis and cellular respiration?Photosynthesis is a metabolic pathway that plants and algae use to generate simple carbs such as glucose by using reactant carbon dioxide, water, and also sunlight.
Conversely, cellular respiration is a series of chemical reactions used by all aerobic cells in order to generate ATP, which is considered the energy coin of the cells. In cellular respiration, the reactants include foods such as glucose molecules and oxygen, while the products of this pathway include carbon dioxide and also the generation of ATP.
Therefore, with this data, we can see that photosynthesis and cellular respiration are different in terms of reactants and products and both metabolic pathways may be considered complementary in terms of the generation and use of substrates.

here is a portion of a hypothetical dna sequence: 3' t t c g a a c c g a g 5' suppose this sequence is part of the template strand of a gene. the sequence of the rna transcript produced from this part of the gene would be:
Answer:
sequence of the RNA transcript produced from this part of the gene would be:
5' A A G C U U G G C U C 3'
Explanation:
The RNA transcript is produced by transcribing the DNA sequence into RNA using the enzyme RNA polymerase. During transcription, RNA polymerase reads the DNA sequence and uses it as a template to synthesize the complementary RNA sequence. Because RNA is single-stranded and DNA is double-stranded, the RNA transcript is complementary to the non-template strand of the DNA, not the template strand.
In the given DNA sequence, the non-template strand would be:
3' A A C G T T G G C T G 5'
The RNA transcript is produced by transcribing this non-template strand, so the resulting RNA sequence would be the complementary sequence:
5' A A G C U U G G C U C 3'
This RNA transcript would be the sequence of the RNA produced from the given DNA sequence.

scientists believe that perching birds originated on the continents of australia and antarctica. how would these scientists explain the discovery of ancient perching bird fossils in africa?
The concept that dinosaurs were the direct ancestors of birds was backed by new research on ancient specimens as well as by field finds of dinosaur and early bird species.
Numerous traits and behaviours that distinguish modern birds were also present in dinosaur forebears. Theropods were a class of meat-eating dinosaurs from which birds descended. Although birds originated from little theropods rather than gigantic ones like Tyrannosaurus rex, they nonetheless belong to the same group as the dinosaur. The earliest fossilised bird remains date back 150 million years. Since they have a foot structure that enables them to grip branches, many bird species, including the majority of songbirds, are also known as "perching birds." The shape of one toe at the back of the foot works as a pincher, stabilising the perched bird.
The complete question is:
Scientists believe that perching birds originated on the continents of Australia and Antarctica. How would these scientists explain the discovery of ancient perching bird fossils in Africa? A) At one time, the climate in Earth was consistent throughout the planet. B) The fossils may have been moved by man, animals, or Earth’s constructive and destructive processes. C) The birds originated in Africa, but migrated with human populations to Australia and Antarctica to Africa. D) During the life of Pangea, Antarctica, Australia and Africa were neighboring

Normal cells have a contact inhibition feedback mechanism that prevents the cells
from replicating when other cells are touched. A diagram of cells with contact
inhibition and cells without contact inhibition is shown.
Which statement best describes what will happen to cells in an organism that lack
contact inhibition?
ANSWER CHOICES
The cells will stop replicating once one layer is produced as other body cells will crowd them out.
The cells replicate into the food supply for each cell is used, causing each cell to die
The cells will continue to grow causing a tumor in the body
The cells will replicate normally replacing body cells that die
The statement that best describes what will happen to cells in an organism that lacks contact inhibition is that the cells will continue to grow to cause a tumor in the body.
The correct option is C.
Contact inhibition refers to a process by which cells that are growing when they come in contact with each other will stop the growth of more cells.
Contact inhibition is a form of feedback inhibition mechanism that enables cells to prevent the excessive growth of cells in the body.
Normal cells have a contact inhibition feedback mechanism. However, some cells lack this feedback mechanism of regulation. Hence, the cells have excessive growth resulting in the formation of tumors.
Examples of cells that lack this feedback mechanism of regulation are cancer cells.

sexual selection in a population choose one: a. can lead to physical differences between the males and females of a species. b. does not lead to evolution. c. reduces genetic variation in the population. d. always favors individuals with a higher survival potential.
The right response is option a, which states that morphological distinctions between males and females of a species can result from sexual selection in a population.
The tail of a peacock is a good illustration of partner selection. Peahens choose peacocks with huge, vibrant tails, which allows those peacocks to mate more frequently and produce younger ones. The genes for a long, colourful tail will be passed down from the father to the male peachicks, who will inherit these genes and develop comparable tails. There are two main factors that influence sexual selection. One is the preference of one sex (typically females) for members of the opposite sex who display particular features. The other is higher strength, which (often in males) results in better success in courting females.
So, we can conclude that option a, which claims that sexual selection can lead to physical differences between males and females of a species in a population, is the appropriate response.

the dna with the gene of interest for a cloning experiment was left on the lab bench overnight (instead of storing it in the freezer). as a result, it was degraded. they didn't know the dna was left out and used it in the experiment. the plasmid, however, was stored correctly. the vector contains a gene for ampicillin resistance. after the transformation procedure, the bacteria were plated on media containing ampicillin. what results are expected from this faulty molecular cloning experiment?
In a molecular cloning procedure, the DNA to be copied is extracted from a target organism and split into smaller DNA fragments in a test tube using enzymes.
These pieces are subsequently joined with vector DNA to produce recombinant DNA molecules. After that, a host organism is given the recombinant DNA (typically an easy-to-grow,strain of E. coli bacteria). Recombinant DNA molecules will be duplicated alongside the host DNA in the resulting population of organisms. These are transgenic or genetically modified organisms because they have foreign DNA pieces. Thus, the term "clone" is frequently used to describe both the bacterial population and the recombinant DNA molecule. In actuality, molecular cloning refers to the scientific techniques utilised to put them together.The idea arose that different DNA sequences could be inserted into a plasmid and that these foreign sequences would be carried into bacteria and digested as part of the plasmid. That is, these plasmids could serve as cloning vectors to carry genes.

The result of the process of meiosis is that it produces increased genetic diversity due to crossing over.
The correct option is C.
What is meiosis?Meiosis is a type of cell division that results in the production of gametes or sex cells. Hence. meiosis is a form of cell division that occurs only during sexual reproduction.
During meiosis, the cells of the parent organism which have a pair of chromosomes or diploid number or 2n of chromosomes divide to produce the gametes which have the haploid number or n number of chromosomes.
Hence, the sex cells or gametes produced can fuse to form a zygote that has a pair of chromosomes or diploid number or 2n of chromosomes.
The process of meiosis results in genetic variation as it allows for the crossing over of genes, such that the genes of the offspring show a variation to that of the parents as well as among the offspring.
