Chapter 14.4, Problem 1R
Summary Introduction
To review:
The reason and the process of pre-mRNA (precursor messenger ribonucleic acid) modification at the 5’-end and 3’-end of the transcript.
Introduction:
Transcription is the process of passing down the genetic information from deoxyribonucleic acid (DNA) molecule to RNA molecule. The process of transcription can be broken into three stages.
