In three dimensional view the molecule of t-RNA is:
- L-shaped
- S-shaped
- Y-shaped
- E-shaped
The Correct Option is A
Solution and Explanation
The tRNA molecule has a distinctive L-shaped three-dimensional structure, with one end containing the amino acid attachment site (where it carries the specific amino acid) and the other end having an anticodon sequence that pairs with the mRNA codon during protein synthesis. This unique L-shape is essential for its role in protein translation.
So, the correct option is (A): L-shaped

Concepts Used:
Translation
The translation is the process of converting nucleic acid information into amino acids. It also relates to the process of producing proteins from mRNA templates.
Components of Translation:
The main components of translation include :
- mRNA of both Eukaryotes and Prokaryotes
- tRNA - It helps in sending commands or transferring the information between protein and nucleic acids.
- Ribosomes - It contains ribosomal RNA and proteins, therefore, it is called the manufacturing unit of a cell.
- Enzymes - It is required for the formation of a peptide bond between the amino acids and also to attach amino acids to the accurate tRNA molecules.
- Proteins - They are the soluble factors, which are required for proper initiation, elongation and termination of translation.
Translation Process:
The three stages of translation are-
- Initiation involves assembling ribosomes around mRNA and activating amino acid and delivering it to the transfer RNA.
- Elongation is the process in which the RNA strand gets longer by adding amino acids.
- The termination process only involves releasing a polypeptide chain.
