Question
Chapter 16.5, Problem 2R
Summary Introduction
To review:
The way in which the three-dimensional structure of mRNA (messenger ribonucleic acids) contributes to the regulation of its expression.
Introduction:
After transcription, the translation of mRNA can be controlled by the activities of proteins. To control the amount of protein formation, the cell regulates translation and the three-dimensional structure of mRNA also plays role in gene expression regulation.
