The final step of gene expression is protein synthesis, which is also known as

  • A.replication
  • B.translation
  • C.transcription
  • D.none of these

Answer: B

Correct answer: translation

Translation is protein synthesis - the ribosome reading the mRNA codons and assembling the corresponding amino acids. The name reflects the change of language: from the four-letter alphabet of nucleic acid to the twenty-letter alphabet of protein. Transcription is DNA to RNA, and replication DNA to DNA.
