NEET Previous Year Question
The process of translation of mRNA to proteins begins as soon as:
Topic: NEET PYQ
Answer: B. Full step-by-step solution below.
- AThe tRNA is activated and the larger subunit of ribosome encounters mRNA
- BThe small subunit of ribosome encounters mRNA
- CThe larger subunit of ribosome encounters mRNA
- DBoth the subunits join together to bind with mRNA
Correct answer: B
Solution
(b) Translation refers to the process of polymerisation of amino acids to form a polypeptide. Ribosome is the cellular factory responsible for synthesis of proteins. The ribosome consists of structural RNAs and about 80 different proteins. In its inactive state, it exists as two subunits; a large subunit and a small subunit. When the small subunit of ribosome encounters an mRNA, the process of translation of the mRNA to protein begins.More Molecular Basis of Inheritance PYQs
