Which of the following is an example of post-translational modification?
Glutamate to Glutamine
Proline to Hydroxyproline
Aspaate to Asparagine
Leucine to Isoleucine
Proline has its own codons, hydroxy proline does not have. hydroxyproline is formed from proline by post-translational modification. Glutamate to glutamine is mutation, not post-translational modification. The same is true for option c and d.
