Question

For translation to take place, which of the following would not be required to be present?

• A. DNA
• B. mRNA
• C. tRNA-amino acid complex
• D. rRNA

Answer 1

The correct option is A DNA

• In translation, messenger RNA (mRNA) is decoded in a ribosome to produce a specific amino acid chain or polypeptide. Thus, for a translation to occur we need mRNA and not DNA.

• Ribosomes are made up of rRNA and proteins.
• Each tRNA after being aminoacyclated (or charged) with a specific amino acid by an aminoacyl tRNA synthetase, carries this amino acid to be incorporated into the growing polypeptide chain.
  

So the correct option is 'DNA'.
