Within a cell, the amount of protein made using a given mRNA molecule depends partly on...
A. the presence of certain transcription factors.
B. the rate at which the mRNA is degraded.
C. the degree of DNA methylation.
D. the number of introns present in the mRNA.



Answer :

The amount of protein produced in a cell utilizing a particular mRNA molecule is somewhat influenced by the rate of mRNA degradation. Here option B is the correct answer.

DNA is converted into mRNA, which joins cytoplasmic ribosomes to act as a template for protein production. There are many levels at which gene expression is regulated.

One such regulatory system is the longevity of mRNA and the pace of its degradation which in turn influences the availability of templates again for the process of protein synthesis and so keeps a check on the overall quantity of protein being generated in a cell.

For instance, bacterial mRNA has a relatively short life cycle, which enables them to swiftly adjust the pattern of protein production in response to environmental changes.
