A gene contains three exons of 300bp, 60bp, and 120bp. This gene codes for two different proteins, one that is160 amino acids long, and a second that is 140 amino acids long. Propose a model of alternative splicing for this gene that can account for these facts.

Answer #1

Alternative splicing, or differential splicing, is a regulated process during gene expression that results in a single gene coding for multiple proteins. In this process, particular exons of a gene may be included within or excluded from the final, processed messenger RNA (mRNA) produced from that gene.

So here in case of proteins with one that is160 amino acids takes origination from all three exons whereas for second amino acids 60 bp get spliced and 140 amino acids protein formed.

    You have carried out a two-hybrid screen with your favorite gene (which codes for your favorite protein YFP) and identified a gene that codes for a protein we’ll call “A.” YFP is only 90 amino acids long. You wish to identify which part of YFP binds to A. You construct three deletion alleles of YFP that are fused Gal4 binding domain, one contains the N-terminal 30 amino acids of YFP (1-30), one the middle 30 amino acids (31-60) and one...
