Which of the following processes is NOT a post -translational modification that occurs in the endoplasmic reticulum or Golgi apparatus to make proteins functional?
A) the addition of lipids
B) the removal of the leader sequence
C) the cleavage of excess amino acids

E) the addition of more amino acids

Question

Quizplus · Accepted Answer

The addition of more amino acids is not considered a post-translational modification process that occurs in the endoplasmic reticulum or Golgi apparatus. Post-translational modifications typically involve the chemical modification of the protein after its synthesis, such as the addition of lipids, carbohydrates, or the cleavage of amino acids or leader sequences, rather than the addition of more amino acids to the polypeptide chain.
