... (i) Binding of tRNAs and formation of peptide bonds between amino acids continues until the ribosomes reaches a stop codon. No tRNA binds to stop codons. Instead, protein “release factors” signal the ribosome to release the newly made protein. The mRNA is also released, and the subunits separate. ...

... Making proteins can be added to mRNAs to make them inactive until required. This is commonly found in animal eggs, keeping the mRNA inactive until after the egg has been fertilized. Another post-transcriptional modification can change the rate of mRNA degradation. The addition of a 5′ cap and a poly ...

... • The code is “ordered” – The first 2 positions are more important – When lining up with the anticodon of the tRNA, the third position doesn’t bind as tightly, thus a looser match is possible. – Because of this flexibility, a cell doesn’t need 61 different tRNAs (one for each codon). • Bacteria have ...
