Question

Map Sapling Learning macmillan Which description applies to alternative mRNA splicing? O processing of exons in mRNA that results in a single gene coding for multiple proteins O mRNA modifications such as additions of a 5 -cap and 3' poly-A tail and removal of introns O protein modifications such as addition of a functional group, or structural changes such as folding O heritable changes in gene expression that occur without altering the DNA sequence O a gene cluster controlled by a single promoter that transcribes to a single mRNA strand

Explanation / Answer

Answer is "processing of exons in mRNA that results in a single gene coding for multiple proteins."

Alternative splicing or differential splicing is a mechanism in geen expression where a single gene could code for multiple proteins. This becomes possible by inclusion or exclusion of exons from the final processed mRNA of that gene. By this method, our genes become capable of producing innumerable combinations of amino acids and thus proteins.
