Describe the three structural components of an RNA nucleotide monomer. Explain the role of RNA polymerase during transcription.

RNA or ribose nucleic acid is a single-stranded nucleotide, which is transcribed from the DNA. The structural components of RNA and the polymerase during transcription play a crucial role in commencing gene expression.

The functions are expressed as:

1. The three structural components of the RNA nucleotide monomer are four nitrogenous bases, a 5-carbon sugar, ribose, and phosphate group. These three components combine to form the nucleotide.

2. The role of RNA polymerase during transcription is that it examines the process of transcription, data drawn into the new molecule of messenger RNA.

Transcription is the first process in regulating gene expression, and RNA synthesis helps in the copying of genetic data from DNA to RNA.

Therefore, RNA is made up of three units, and polymerase regulates gene expression.

2.The role of RNA polymerase during transcription:

it provides an alternative energy pathway for the reaction to proceed.

a catalyst is a substance that speeds up the rate of a chemical reaction but is not consumed during the course of the reaction.

catalysts increase the rate of reaction without being used up. they do this by lowering the activation energy needed. with a catalyst, more collisions result in a reaction, so the rate of reaction increases. different reactions need different catalysts.

a catalyst works by providing an alternative reaction pathway to the reaction product. the rate of the reaction is increased as this alternative route has a lower activation energy than the reaction route not mediated by the catalyst.
