Webb30 juni 2024 · Ribosomes, either free in the cytosol or associated with rER, synthesize proteins as polypeptide chains. This occurs through the translation of RNA. Specifically, ribosomes bind to messenger RNA, abbreviated mRNA. The ribosome reads a series of nucleotide bases in groups of three called codons. The first codon read is the start codon.
