Transcription and RNA Processing · Zoology

Alternative splicing is a mechanism that allows for which of the following?

  1. Increased rate of chromosomal DNA replication
  2. Multiple protein isoforms from one gene
  3. Reverse transcription of RNA back to DNA
  4. Correction of point mutations within coding exons
Show answer and explanation

Correct answer: Multiple protein isoforms from one gene

Alternative splicing selectively includes or excludes different exons from the same pre-mRNA. A single gene can thereby produce multiple distinct protein isoforms, greatly expanding the proteome beyond what gene number alone would predict.
