Answer:
A single antibody gene can code for different related proteins, depending on the splicing that takes place post-transcriptionally.
Explanation:
According to the "one-gene, one-enzyme hypothesis", a gene code for single specific enzyme only. Beadle and Tatum proposed the one-gene, one-enzyme hypothesis that states that a gene encodes the genetic information for the synthesis of one enzyme only. However, alternative splicing in eukaryotes allows the formation of more than one related proteins/enzymes from a single gene.
For instance, alternative splicing of single primary transcript transcribed from an antibody gene allows the formation of multiple proteins. The primary transcript encoded by this gene has a segment of the gene that serves as either intron or exon. Depending on particular combinations of exons retained after splicing, multiple related proteins are formed by respective mRNA.
Answer:
Cells of skin, for instance, have highest mitotic index.
Explanation:
Many cells are capable of dividing rapidly. <u>For example</u>, in plants, the cells near the root tip in the apical meristem divide rapidly to push through the soil because the root cap detects the gravity and direct rapid division and growth of cells near the tip.
If we take muscle, skin, kidney, and lung as examples that are given in real question, <u>skin cells have the highest mitotic index because they need to get replaced most frequently</u>.
