Answer:
A. Alternative mRNA Splicing
Explanation:
The primary transcript of eukaryotes has introns and exons. The post-transcriptional modification includes splicing of introns and joining of exons to form a mature mRNA.
A single gene can specify two or more related proteins due to the process of alternative splicing of mRNA wherein exons are removed and joined in various combinations which in turn serve as the template for different proteins.
For example, if a primary transcript has 7 exons, the mature mRNA may have all 7 exons or some of them in various combinations. The resultant mRNAs with different combinations of exons would specify different proteins.
I found the exercise on the internet and these are the options:
"<span>a. gluconeogenesis begins
b. beta-oxidation increases
c. blood glucose levels fall
d. the liver produces more glycogen"
The option that's not likely to happen is "</span>the liver produces more glycogen".
The formation of glycogen by the liver happens after eating a meal with carbohydrates. The level of blood glucose increases, and insulin is secreted by the pancreas and will act by allowing glucose to enter the body cells. When the glucose enters the liver cells, insulin will also act on the liver by stimulating glycogen synthesis. This process continues to happen until glucose levels begin to decrease in the <span>post-absorptive state</span> and, therefore, insulin secretion also decreases leading glycogen synthesis in the liver to stop.
