The first step of protein synthesis is that **DNA unzips between the base pairs**. This process allows for the transcription of mRNA from the DNA template, which is essential before translation can occur and amino acids can be linked to form proteins.

Yes, I can clarify that for you. The correct sequence of events in protein synthesis starts with the transcription of DNA into mRNA, which involves the unzipping of the DNA strands. Once the mRNA is synthesized, then **a ribosome attaches to the mRNA** to initiate translation.
So, while "a ribosome attaches to the mRNA" is a crucial step in the process, it actually occurs after the initial step of DNA unzipping and mRNA synthesis. Therefore, the first step is indeed that **DNA unzips between the base pairs.**
