Worked practice questions

**Introns** in eukaryotic primary transcripts are:

  1. Removed by splicing before mRNA is exported to cytoplasm
  2. Retained in the mature mRNA
  3. Translated into a signal peptide
  4. Found only in tRNA
Show answer and solution

Correct answer: A. Removed by splicing before mRNA is exported to cytoplasm

hnRNA contains both **exons** (coding) and **introns** (non-coding). During processing, introns are spliced out and exons joined (by spliceosome / DNA ligase-like activity), capping and tailing follow, producing the mature mRNA — which is then exported and translated.
