Which process is the first step of protein synthesis? a. transcription b. replication c. conjugation d. translation

Correct A. Transcription

Explanation:

The first step in protein synthesis is transcription. In this step, the two strands in double DNA helix are separated and one of them is used as a model: an RNA sequence is synthesized from the original DNA.

Then, in a second step, this mRNA (messenger ribonucleic acid) will be used by ribosomes to make an amino acid sequence (primary protein structure).
