Answer:
The correct answer will be option- Insulin.
Explanation:
Gluconeogenesis is the process of formation of sugar glucose from the non-carbohydrate sources during the less or no intake of carbohydrate from the diet.
Gluconeogenesis is controlled by a feedback mechanism which could be positive or negative. The positive feedback is controlled by the hormones like epinephrine, cortisol and glucagon but insulin shows negative feedback mechanism and inhibit the process.
Thus, option- Insulin is the correct answer.
Proteins synthesis requires transcription of DNA (containing information) to mRNA then this goes out of the cell’s nucleus to cytoplasm; and translation of mRNA together with ribosome and tRNA to synthesize proteins. Further steps are the following: 1) One side of DNA strand is copied to become mRNA (messenger RNA). 2) mRNA goes out the cell’s nucleus, next to cytoplasm and then to ribosome. 3) mRNA works with ribosome’s 3 bases at the same time. 4) tRNA (transfer RNA) connects with available DNA bases. <span>5) tRNA releases the amino acids which in turn combines with the other produced amino acid chains from different DNAs. </span>
A community of organisms would have a down fall due to an unbalance in the food chain. Since a Grizzly bear is a third tropic level consumer, there would be an increase in tertiary consumers. This would then cause all the other level in a decrease in population due to over eaten.
Length of PolyA tail is different in two cells
Explanation:
- Different lengths of Poly A tails are present for different mRNAs so when we compare two peptides translated in two different cells we have different lengths of PolyA tail
- PolyA tail is basically a long chain of nucleotides(adenine nucleotides) which are added to messenger RNA(mRNA) during processing of RNA
- It increases the stability of the molecule
- It protects the mRNA molecule from undergoing degradation in the cytoplasm
- It is involved in binding proteins which further initiates translation;introns are removed from pre mRNA before the final mRNA is exported into cytoplasm
