Answer:
b. the rate at which the mRNA is degraded.
Explanation:
DNA is transcribed into mRNA which then joins ribosomes present in the cytoplasm to serve as a template for protein synthesis. Regulation of gene expression occurs at several levels.
One such regulatory mechanism is the stability of mRNA and the rate of its degradation which in turn affects the availability of template for the process of protein synthesis and thereby keeps a check on the total amount of protein being formed in a cell.
For example, a very short life span of bacterial mRNA (few minutes) allows them to regulate the pattern of protein synthesis quickly in response to the changes in surroundings.
A minimum stream velocity <span>needed to keep a 6.4 cm diameter particle in motion must be 100 cm/s.
It can be concluded from Hjulstrome curve, a graph used to determine whether stream will transport, erode or deposit particles. The faster is the current, the heavier particles it could transport.</span>
Answer: B
Explanation:
The way something is arranged enables it to play its role, fulfill its job, within an organism (a living thing). Structure-function relationships arise through the process of natural selection.
