Question

Identify the correct matching pair.

$\begin{array}{cccc}& \text{Type of RNA}& \text{Form}& \text{Function}\\ \text{I}& \text{mRNA}& \text{Messenger}& \text{carrier of information to ribosomes}\\ \text{II}& \text{rRNA}& \text{Ribosomal}& \text{initiates synthesis of proteins}\\ \text{III}& \text{tRNA}& \text{Transfer}& \text{Transport of amino acids to ribosomes}\end{array}$

• A. $I,II\&III$
• B. $I$
• C. $II$
• D. $III$

Answer 1

The correct option is A

$I,II\&III$

mRNA or messenger RNA is the RNA molecule produced by the transcription of DNA and is the molecule involved in carrying the information about the proteins, or the protein code from DNA to ribosomes for protein synthesis. tRNA or transfer RNA molecule carries the specific amino acids from the amino acid pool to the ribosomes, for protein synthesis. And rRNA or ribosomal RNA are RNA molecules in ribosomes, these are involved in the ribosomal activity, that is in the translation process or in other words in protein synthesis. rRNAs are involved in the binding of mRNA to the ribosomes and thus initiate protein synthesis.
