Problem: Which description applies to alternative mRNA splicing?a) Protein modifications such as addition of a functional group, or structural changes such as folding.b) Heritable changes in gene expression that occur without altering the DNA sequence.c) A gene cluster controlled by a single promoter that transcribes to a single mRNA strand.d) mRNA modifications such as additions of a 5'-cap and 3' poly-A tail and removal of introns.e) Processing of exons in mRNA that results in a single gene coding for multiple proteins.

RNA Splicing: involves removal of introns and recombining exons

introns (intervening sequences): do not code for proteins; usually contain regulatory regions for transcription

exons (expressed sequences): code for proteins
