Question

What are the types of $RNA$ molecules which perform different functions?

Answer 1

Hint: Our body consists of various body parts, each body part is different from body part of others like colour of eye, height, etc. these all unique qualities are determined by our genes, and the coding, decoding, regulation and expression of these genes is done by a special polymeric molecule called RNA.

Complete step by step answer:
RNA (Ribonucleic acid) is a polymeric molecule essential in various biological roles in coding, decoding, regulation and expression of genes. RNA is nucleic acid, the primary function of RNA is to convert the information stored in DNA into proteins.
There are three types of RNA molecules:
Messenger RNA ($mRNA$)
$mRNA$ transcribes the genetic code from DNA into a form that can be read and used to make proteins. $mRNA$ carries genetic information.
Ribosomal RNA ($rRNA$)
$rRNA$ is found in the cytoplasm of the cell. The direction of translation of $mRNA$ into proteins is done by $rRNA$.
Transfer RNA ($tRNA$)
$tRNA$ is also located in the cytoplasm of a cell, it is used in synthesis of protein. Its basic function is to transfer amino acids to ribosomes.
Hence, the three type of RNA molecules with different-different functions are $mRNA$, $rRNA$ and $tRNA$.

Note: RNA molecules are used as catalysts, they catalyze specific biochemical reactions (reactions in which transformation of one molecule into another molecule takes place in a cell). Its working is similar to that of protein enzymes.
