Question

Consider the following statements. Pick the wrong statement.

• A. $rRNA$ provides the template for synthesis of proteins.
• B. $tRNA$ bring amino acids and reads the genetic code.
• C. $RNA$ polymerase binds to promoter and initiates transcription.
• D. A segment of $DNA$ not coding for a polypeptide is called intron.

Answer 1

The correct option is A $rRNA$ provides the template for synthesis of proteins.

mRNA or messenger RNA provides the template for synthesis of proteins. The ribosome sits on the mRNA transcript and translation is carried to synthesize the polypeptide chain.

A segment of DNA coding for the polypeptide is called exon.

So, the correct statement is 'mRNAprovides the template for synthesis of proteins'.
