Answer:
Alternative splicing explains how it works
Explanation:
Two different transcripts can be produced from one single gene according to the nature of exons and introns of every transcript, which means that a group of exons will form the future mRNA molecule. The nature of this phenomenon is based on the function and local that every transcript will act. These mRNA transcripts are the result of how the RNA polymerase and transcription factors interacts with DNA molecule and therefore selects the number and the size of the exons and introns of each mature mRNA transcript.
Answer:
The correct answer is C) There is a larger variety of MHC proteins that can be expressed on the cell surfaces of their immune cells, providing a wider opportunity to recognize and attack pathogens.
Explanation:
Sister chromatids are two identical copies of Chromosome that is formed by the replication of a single chromosome.
This copies are formed during mitosis. Later on, these two sisters chromatids will grown into two different Cells
