Question

RNA molecules are of three types which are based on their different functions. These are:

• A. messenger RNA, translational RNA, structural RNA
• B. cytosine RNA, nucleoside RNA, nucleotide RNA
• C. messenger RNA, ribosomal RNA, transfer RNA
• D. primary RNA, secondary RNA, tertiary RNA

Answer 1

The correct option is C messenger RNA, ribosomal RNA, transfer RNA

There are 3 types of RNA, each encoded by its own type of gene:

mRNA - Messenger RNA $\to$ Encodes the amino acid sequence of a polypeptide.

tRNA - Transfer RNA $\to$ Brings amino acids to ribosomes during translation.

rRNA - Ribosomal RNA $\to$ With ribosomal proteins, makes up the ribosomes, the organelles that translate the mRNA.
