Question

What is the post-translational modification?

Answer 1

Post-translational modification:

1. Post-translational modification is a stage in the production of proteins.
2. Ribosomes convert mRNA into polypeptide chains, which are then translated into proteins.
3. The polypeptides undergo post-translational modification, such as cutting, folding, and other related processes, before becoming the full protein product.
4. Lipids produced by the smooth endoplasmic reticulum and proteins produced by the rough endoplasmic reticulum both enter the Golgi apparatus' cisternae.
5. They add oligosaccharides or polysaccharides to generate glycolipids and glycoproteins.
6. This process is known as glycosylation.
