Question

The site of t-RNA synthesis:

• A. Cytoplasm
• B. Nucleus
• C. Ribosome
• D. Centrosome

Hint:

t-RNA is synthesized in the nucleus and is then used in the cytoplasm for translating mRNA into proteins.

Answer 1

The Correct Option is B

The nucleus is the site of t-RNA synthesis. t-RNA (transfer RNA) is transcribed from DNA in the nucleus of eukaryotic cells. It is then transported to the cytoplasm, where it plays a critical role in protein synthesis by matching amino acids to the corresponding codons on the mRNA during translation. Here’s the role of other options:
- Cytoplasm: While t-RNA functions in the cytoplasm, the synthesis of t-RNA actually takes place in the nucleus.
- Ribosome: Ribosomes are involved in protein synthesis and translation but are not the site of t-RNA synthesis.
- Centrosome: The centrosome plays a role in cell division but does not participate in t-RNA synthesis. Thus, the correct site for t-RNA synthesis is the nucleus.
