Question

What is 'RNA'? Explain different types of non-genetic RNA with diagrams and functions.

Answer 1

RNA is ribonucleic acid made up of ribonucleotides. The ribonucleotides are made up of the ribose sugar, phosphoric acid, and nitrogenous bases. The nitrogenous bases which are a component of ribonucleotides are adenine, guanine, cytosine, and uracil.

There are three non-genetic type of RNA

mRNA: This form of RNA is encoded by the DNA and contains codons for proteins.

tRNA: This RNA carries the specific amino acid as per the codon on the mRNA during protein synthesis.

rRNA: This RNA codes for ribosomal protein units.
