Describe the role of a ribosome in the production of a polypeptide.
The ribosome acts as a translator, by binding to an mRNA and 'reading' the codon codeA codon is 3 bases on an mRNA, and each codon encodes an amino acidThe ribosome brings the tRNAs with the correct anticodons to each codonAttached to each tRNA is an amino acidThe ribosome catalyses the formation of peptide bonds between the amino acidsMultiple amino acids are attached to produce a polypeptide.
