Post-translation or Post-translational regulation refers to the control of the levels of active protein either by means of reversible events (Post-translational modifications, such as Phosphorylation or sequestration) or by means of irreversible events (proteolysis).

Post translational modification occurs in which cell organelle?
Post translational modification occurs in ribosomes.
What is DNAse?
DNase (deoxyribonuclease) is an enzyme. It is manufactured by ribosomes and can undergo post translational modifications or cotranslational modifications. DNase catalyzes the hydrolytic cleavage of phosphodiester linkages in the DNA backbone. A wide variety of is known, which differ in their substrate specificities, chemical mechanisms, and biological functions.
Eukaryotes show which kinds of control mechanisms is it transcriptional transcript processing translational post translational or all of these?
all
Why the bacteria don't have post translational modifications?
They in fact do. Check out a review "Postranslational Protein Modification in Archaea" by Jerry Eichler. The problem is that took a long time to discover this so it was assumed that they don't have any PTMs but this is wrong.
What is the degradation and synthesis of protein called?
denaturation for degradation synthesis: first step is Transcription, The second step is Translation; there are additional steps (post-translational modifications) after that the polypeptide is formed including the formation of 3D conformation
What has the author Franco A Taverna written?
Franco A. Taverna has written: 'The role of post-translational modifications in the structure and function of glutamate receptors'

Why prokaryotic cells are not prefer for eukaryotic gene expression?
Actually, for some uses prokaryotic cells are just fine for eukaryotic gene expression. That said bacteria are deficient in quite a lot of the post-translational modification systems that eukaryotes use, such as glycosylation. Since those post-translational modifications can actually be important to the protein's function you might choose a eukaryotic expression system to preserve them.

Differentiation is controlled at which level?
Post translational activation of the proteins
What are three types of post-translational modification?
methylation lipidation glycosylation phosphorylation

Why prokaryotes cannot perform post translational process?
No endoplasmic reticulum and no Golgi apparatus.
What levels of gene expression control allows a cell to respond most rapidly to a changing environment?
post-translational control can respond most rapidly, despite being extremely inefficient.
Which aspect of lac operon regulation is an example of post-translational control?
allosteric regulation of CAP
