Answer:
The explanation is the answer.
Explanation:
RNA consists of ribose nucleotides (nitrogenous bases appended to a ribose sugar) attached by phosphodiester bonds, forming strands of varying lengths. The nitrogenous bases in RNA are adenine, guanine, cytosine, and uracil, which replaces thymine in DNA.
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.
RNA polymerase is an enzyme that is responsible for copying a DNA sequence into an RNA sequence, the process of transcription.
Thus, these are the components.
