Small links bound together to form proteins
WebThe ribosome is composed of a small and large subunit. The small subunit binds to an mRNA transcript and both subunits come together to provide three locations for tRNAs to bind (the A site, P site, and E site). In the … WebRibosomes link amino acids together in the order specified by the codons of messenger RNA (mRNA) molecules to form polypeptide chains. Ribosomes consist of two major components: the small and large ribosomal subunits. Each subunit consists of one or more ribosomal RNA (rRNA) molecules and many ribosomal proteins (RPs or r-proteins).
