Question
Chapter 12, Problem 9CONQ
Summary Introduction
To review:
The RNA (ribonucleic acid) polymerase subunit and its composition. And, the different roles of subunits present in RNA.
Introduction:
The DNA (deoxyribonucleic acid) sequences consist of a few functional promoters. The RNA strand is formed after transcription and this strand consists of many enzymes which help it to bind to the DNA. This helps the RNA strand in creating the protein sequence. The amino acids join to the strand of mRNA.
