A transversion somewhere within gene "B" in a laboratory plant results in the production of a mutant mRNA that is much longer than the wild type.This transversion is most likely located:
A)downstream of the STOP codon,in the last exon of gene "B."
B)in an intron of gene "B" away from the splice sites.
C)in the open reading frame of gene "B."
D)within a splice site of gene "B."
E)within the promoter of gene "B."

Question

Quizplus · Accepted Answer

A transversion within a splice site of gene "B" can lead to improper splicing, potentially causing the inclusion of introns or the exclusion of exons in the final mRNA transcript. This can result in a longer mRNA molecule compared to the wild type.
