Final answer:
The first step of protein synthesis is transcription, where the DNA code is copied into mRNA for further processing at the ribosome.
Explanation:
The first step of protein synthesis is transcription.
During transcription, the genetic code of DNA is copied into messenger RNA (mRNA). It is the initial process in protein synthesis where mRNA carries the genetic information from the nucleus to the ribosome.
Initiation, noted as the first phase of protein synthesis, brings together the ribosome, mRNA, and initiator tRNA to form an initiation complex.
