Alternative splicing can generate more than one polypeptide from a single gene by Select one: a. cleaving the polypeptide at different positions. b. changing the order of exons included in the mature mRNA. c. omitting specific exons from the mature mRNA. d. incorporating different amino acids at a single codon position.
Eukaryotic nacent mRNA contain both protein coding regions called exons and non coding regions called introns. Splicing is the process of editing this nacent mRNA (pre mRNA) into mature mRNA. After the splicing is over, introns are removed and exons are joined.This mRNA undergo translation and thus proteins are formed. Alternative splicing is the most important form of splicing found in mammals. It is the process in which some of the exons within the pre mRNA are skipped or joined differently resulting in multiple proteins gnerated from single gene. Thus alternative splicing results in proteomic diversity in humans, affects various functions in cellular processes.
Alternate splicing can occur in different ways which include exon skipping or alternate exon selection.Therefore answer can be b and c
Answer is b and c
(but changing the order of exons included in the mature mRNA (not mature mRNA but nacent mRNA). c. omitting specific exons from the mature mRNA.(not mature mRNA but nacent mRNA)
