The structural components of an RNA and the role of the polymerase during transcription is explained below and the nucleotide is formed by the chemical substances and the polymerase plays a role in commencing to the gene expression.
<u>Explanation:</u>
<u>1.Three structural components of an RNA nucleotide monomer:</u>
A nucleotide is formed by the three unique chemical substances namely a 5-carbon sugar molecule, a nitrogenous base, and a phosphate group with all these three combinations the nucleotide is formed.
<u>2.The role of RNA polymerase during transcription:</u>
<u></u>RNA polymerase examines the method of transcription, through which the data collected in a molecule of DNA is drawn into a new molecule of messenger RNA.
This transcription is the first round commencing to gene expression.
RNA synthesis is provided out by proteins and that copies the genetic data from DNA in a very organized, multi-stage method
