Question

Draw and label diagram of tRNA.

Answer 1

Structure of tRNA:

1. Transfer RNA (tRNA) is a tiny, well-studied RNA molecule that is essential for the creation of proteins.
2. Adaptor RNA is another name for transfer RNA.
3. It is a single RNA chain with 73–93 nucleotides that is found in the organelles and cytoplasm of every live cell.
4. The tRNA's cloverleaf structure includes distinct stems and loops for the acceptor arm, anticodon stem and loop, variable arm, T-stem and loop ,D-stem and loop.
5. The CCA sequence and 4 single-stranded nucleotides, along with 7 base pairs, are always present in the acceptor stem.
6. The D stem and loop are changeable in length, but the anticodon stem and loop are fixed at 5 base pairs and 7 nucleotides, respectively.
7. The T-loop always has 7 nucleotides, while the T-stem always has 5 base pairs.
8. The variable arm typically contains 4-5 nucleotides, although it can also have up to 24.
9. A messenger RNA strand is translated into a protein with the aid of transfer RNA.
