Question

Choose the correct answers from the alternatives given :
The base sequence known as the anticodon is part of a

• A. ribosomal RNA
• B. transfer RNA
• C. messenger RNA
• D. DNA

Answer 1

The correct option is B transfer RNA

Transfer RNA or tRNA molecule is a cloverleaf-like structure that has four arms. These four arms include:

1. Acceptor arm consists of base-paired stem whose free OH group can be linked to an amino acid.

2. TC arm that is named for the presence of the triplet sequence containing pseudouridine.

3. Anticodon arm always contains the anticodon triplet in the centre of the loop which is complementary to the sequence on the mRNA.

4. D arm is named for its content of base dihydrouridine.

So, the correct option is 'transfer RNA'.
