Question

Can different combinations of exons be spliced together to generate different mature mRNAs? A) No, exons are fixed in their positions B) Yes, different combinations of exons can be spliced together to generate different mature mRNAs C) Only in prokaryotic cells D) Only in eukaryotic cells

Answer 1

B) Yes, different combinations of exons can be spliced together to generate different mature mRNAs.

Step-by-step explanation:

This process is known as alternative splicing, and it is a common mechanism in eukaryotic cells that allows for the generation of multiple different mRNA transcripts from a single gene. Different combinations of exons can be included or excluded during splicing, resulting in various mature mRNA molecules with potentially different protein-coding sequences or functions. This contributes to the diversity of proteins that can be produced from a single gene.
