Common mistakes in Translation at the ribosome
Recorded against questions in this topic that are not shown above, so none of these points at an answer you can see on this page.
- Assuming every codon change simply substitutes one amino acid for another.
- Assumes a stop codon simply specifies another amino acid.
- Assumes codon grouping can shift without changing the translated sequence.
