Which of the following is produced as a result of alternative splicing during RNA processing?
A
A single, unmodified mRNA transcript
B
Only non-coding RNAs
C
Multiple distinct mRNA variants from a single gene
D
Identical proteins from different genes
Verified step by step guidance1
Understand that alternative splicing is a process during RNA processing where different combinations of exons are joined together from the same pre-mRNA transcript.
Recognize that this process allows a single gene to produce multiple distinct mRNA variants by including or excluding certain exons.
Recall that these different mRNA variants can then be translated into different protein isoforms, increasing protein diversity without increasing the number of genes.
Note that alternative splicing does not produce a single, unmodified mRNA transcript, nor does it produce only non-coding RNAs or identical proteins from different genes.
Conclude that the correct outcome of alternative splicing is multiple distinct mRNA variants from a single gene.
