Respuesta :
Correct statement about introns and exons is (a) The number of introns is always less than the number of exons in a gene.
An intron is a region that is located inside a gene but does not stay in the final, mature mRNA molecule after that gene is translated and does not code for the amino acids that make up the protein that that gene is responsible for encoding.
The most important role of introns in protein synthesis is to allow alternative splicing, which allows for the production of several proteins from a single gene. After being spliced, some introns undergo further processing in order to produce functional RNA molecules.
A gene's exons are the regions that code for proteins. Amino acids are coded for in exons, which are found in mRNA.A variety of exons code for various protein domains. The domains might be encoded by a single exon or by splicing together several exons.
