What process converts the mRNA "message" into a sequence of amino acids?

Question

BlackTom AI · Accepted Answer

The question asks: what process converts the mRNA 'message' into a sequence of amino acids?

First, consider the major cellular information-flow steps to map processes to outcomes:
- Transcription: the synthesis of mRNA from a DNA template. This step creates the messenger RNA that carries genetic information, but it does not determine the amino acid sequence of a protein directly.
- Translation: the decoding of the mRNA message to assemble a chain of amino acids, forming a polypeptide. This occurs at the ribosome with tRNA delivering specific amino acids according to codon sequences in the mRNA.
- Replication: the copying of DNA, ensuring genetic material is passed on during cell division. This is unrelated to directly producing a protein sequence from mRNA.
- Post-translational modification: after translation, polypeptides may be modified (folding, phosphorylation, glycosylation, etc.), but this step occurs after the amino acid sequence is already synthesized.

Given these distinctions, translation is the process that directly converts the information encoded in mRNA codons into a corresponding sequence of amino acids, via codon–anticodon recognition and the sequential addition of amino acids carried by tRNA molecules.

Common incorrect options (if presented) would typically include transcription, which would be misidentifying the step by confusing RNA synthesis with protein synthesis; replication, which would be about copying DNA rather than interpreting RNA; or post-translational modification, which occurs after amino acids are already linked in a polypeptide chain.

Even without listed options here, the conceptual answer aligns with translation as the decoder of mRNA into amino acid sequences, rather than the synthesis of mRNA (transcription) or the copying of DNA (replication), or modification after synthesis (post-translational changes).
