WebbThe site of protein synthesis is the ribosome. Ribosomes are interesting structures in that they are a combination of RNA and protein. The form of RNA that is found in a ribosome is ribosomal RNA, or rRNA. Source: Pearson Education. Translation occurs in three major steps: (1) initiation. (2) elongation, and (3) termination. Webb1 mars 2024 · Initiation begins with the small ribosomal subunit binding to the 5’ end of the mRNA, the messenger RNA created in transcription from DNA. This occurs in two stages: the small ribosomal subunit first binds to several proteinaceous initiation factors, before the combined structure binds to mRNA.
