Summary Introduction
To review:
Definition of the following terminologies:
mRNA scanning
Transcript localization
Glycosylation
Targeting
Lipophilic modification
Introduction:
Messenger ribonucleic acid (mRNA) scanning, transcript localization, glycosylation, targeting, and lipophilic modification are related to the synthesis of proteinsand their subsequent fate. This occurs in the cellular cytoplasm.
