Question

Enlist the types of RNA. Discuss various structural features of each.

Answer 1

1) MRNA - Messenger RNA: Encodes amino acid sequence of a polypeptide.

2) TRNA - Transfer RNA: Brings amino acids to ribosomes during translation.

3) RRNA - Ribosomal RNA: With ribosomal proteins, makes up the ribosomes, the organelles that translate the mRNA.

4) SNRNA - Small nuclear RNA: With proteins, forms complexes that are used in RNA processing in eukaryotes. (Not found in prokaryotes.)

$\Huge{\mathcal{\green{\underline{Answer}}}}$

✔️There are 4 types of RNA, each encoded by its own type of gene.

✔️The genomic DNA contains all the information for the structure and function of an organism.

✔️In any cell, only some of the genes are expressed, that is, transcribed into RNA.
