Chapter 11.1, Problem 1TYK
Summary Introduction
Introduction:
The ncRNA is a noncoding RNA. These are the RNA molecules that do not encode for the polypeptide. The ncRNA can bind with different kinds of molecules and perform different functions such as scaffold, ribozyme, and altering the protein function.
