Genes encode proteins and proteins dictate cell function. Therefore, the thousands of genes expressed in a particular cell determine what that cell can do. Moreover, each step in the flow of information from DNA to RNA to protein provides the cell with a potential control point for self-regulating its functions by adjusting the amount and type of proteins it manufactures.
At any given time, the amount of a particular protein in a cell reflects the balance between that protein's synthetic and degradative biochemical pathways. On the synthetic side of this balance, recall that protein production starts at transcription (DNA to RNA) and continues with translation (RNA to protein). Thus, control of these processes plays a critical role in determining what proteins are present in a cell and in what amounts. In addition, the way in which a cell processes its RNA transcripts and newly made proteins also greatly influences protein levels.
Answer:
Option A and C and D
Explanation:
Gylcogen is synthesized through a series of reactions through the assistance of enzymes. When glucose enter into the cell, it is converted into glucose 6-phosphate and then into glucose 1-phosphate and finally into uridine 5ʹ-diphosphate-glucose. In glycogenesis, glycogen is broken down into glucose 1-phosphate with the help of two glycogen phosphorylase. In the next stage the glycogen debranching enzyme untangles the branch points.
Hence, option A and C and D are correct
In animals and plants, there are two pairs of chromosomes - one set from a male and the other set from a female. But occasionally, the original fertilized cell doesn't quite divide correctly and more than two sets arises. The fertilized cell continues to divide with the result that all the cells have the extra set of chromosomes. This happens much oftener in plants and the plant will be sterile and can't form seeds.
The endocrine system is a collection of glands that regulate your metabolism, growth, sleep, mood and other things around your body.
