Question

what are the types of RNA? Mention the role of each class of RNA.​

Answer 1

Here's ur answer buddy!!

The 3 Types of RNA and Their Functions ::-

The three main types of ribonucleic acid or RNA are messenger RNA (mRNA), transfer RNA (tRNA), and ribosomal RNA (rRNA).

There are several types of ribonucleic acid, or RNA, but most RNA falls into one of three categories.

# mRNA or Messenger RNA :-

mRNA transcribes the genetic code from DNA into a form that can be read and used to make proteins. mRNA carries genetic information from the nucleus to the cytoplasm of a cell.

# rRNA or Ribosomal RNA :-

rRNA is located in the cytoplasm of a cell, where ribosomes are found. rRNA directs the translation of mRNA into proteins.

# tRNA or Transfer RNA :-

Like rRNA, tRNA is located in the cellular cytoplasm and is involved in protein synthesis. Transfer RNA brings or transfers amino acids to the ribosome that corresponds to each three-nucleotide codon of rRNA. The amino acids then can be joined together and processed to make polypeptides and proteins.

Answer 2

RNA molecules are classified according to their structure and function into three major types,

(I) Ribosomal RNA (rRNA)

(II) Messenger RNA (mRNA)

(III) Transfer RNA (tRNA)
