Question

Which highly expressed protein enhances genes and promotes alternative splicing with exon 9 exclusion and exon 10 retention?

a) hnRNP A1
b) RNA polymerase II
c) Spliceosome
d) Ribosomal protein S2

Answer 1

A) hnRNP A1 is the highly expressed protein that enhances genes and promotes alternative splicing with exon 9 exclusion and exon 10 retention.

Step-by-step explanation:

The highly expressed protein that enhances genes and promotes alternative splicing with exon 9 exclusion and exon 10 retention is a) hnRNP A1.

This protein belongs to a class of proteins known as heterogeneous nuclear ribonucleoproteins (hnRNPs) and plays a role in RNA processing and splicing.

hnRNP A1 binds to specific sequences on pre-mRNA and regulates alternative splicing by influencing which exons are included or excluded in the final mRNA transcript.
