A nonsense mutation has occurred, resulting in a truncated, nonfunctional product in the mutant. In a eukaryotic cell, a gene that is initially transcribed is 1500 nucleotides in length. The mature mRNA for the product is 1200 nucleotides in length. What is the most probable reason for the discrepancy?

Explanation:

the reduction in the sequence is as a result of the removal of introns. Introns are actually non-coding regions and do not code for proteins. they are usually spliced out.
