WebbTranslation is the process by which the genetic information carried by mRNA is used to synthesize a protein. In eukaryotes, translation occurs in the cytoplasm and involves three main steps: initiation, elongation, and termination. Initiation: The small subunit of the ribosome binds to the 5' cap structure of the mRNA, and the ribosome scans ...
