The site of protein synthesis in the cell is the ribosome.

Here's a breakdown:

* Ribosomes: These are complex molecular machines found in all living cells. They are composed of ribosomal RNA (rRNA) and proteins. Ribosomes read the genetic code carried by messenger RNA (mRNA) and use it to assemble amino acids into polypeptide chains, which fold into functional proteins.

* Other components involved:

* mRNA: Carries the genetic code from DNA in the nucleus to the ribosomes.

* tRNA: Transfers specific amino acids to the ribosome based on the codons in the mRNA.
