Answer:
B. mRNA processing events that lead to different types of exons being spliced
together
Step-by-step explanation:
Alternative splicing is a biological term that describes the process of RNA whereby changing the genomic instructions into functional proteins is vital.
One of the most common examples of alternative splicing is the Dscam gene in Drosophilia (8), in which single gene contains some 116 exons of which 17 are retained in the final mRNA.
The purpose of Alternative splicing is to plays a critical role in the regulation of gene expression and protein diversity in a variety of eukaryotes. In humans, approximately 95% of multi-exon genes undergo alternative splicing.
