Question

Site of tRNA that binds to the mRNA molecule is

• A.
  Codon
• B.
  5’ end
• C.
  Anticodon
• D.
  3’ end

Answer 1

The correct option is C

Anticodon
tRNA structure
tRNA or transfer RNA is a type of RNA that carries and transfers amino acids to ribosomes during the synthesis of polypeptides in translation. It consists of the following parts: 5’ end 3’end Anticodon

5’ end
The 5’ end of tRNA remains normally free.

3’ end
The 3’ end of tRNA binds to the amino acid. It requires ATP for amino acid binding. Thus, this process of attachment of an amino acid to the 3’ end of tRNA is called charging of tRNA or aminoacylation of tRNA.

Anticodon
Anticodon loop of tRNA has bases which form hydrogen bonds with the codons on the mRNA. Anticodons are complementary to the codons on the mRNA.
