The process of translation of mRNA to proteins begins as soon as:
Updated On: Aug 3, 2024
- The small subunit of ribosome encounters mRNA
- The larger subunit of ribosome encounters mRNA
- Both the subunits join together to bind with mRNA
- The tRNA is activated and the larger subunit of ribosome encounters mRNA
Hide Solution
Verified By Collegedunia
The Correct Option is A
Solution and Explanation
The initiation of protein synthesis or mRNA translation occurs when the mRNA molecule is encountered by the small subunit of the ribosome.

Questions Asked in NEET exam
- Given below are two statements: one is labelled as Assertion A and the other is labelled as Reason R.
Assertion A : The potential (V) at any axial point, at 2 m distance(r) from the centre of the dipole of dipole moment vector \(\vec{P}\) of magnitude, 4 × 10-6 C m, is ± 9 × 103 V.
(Take \(\frac{1}{4\pi\epsilon_0}=9\times10^9\) SI units)
Reason R : \(V=±\frac{2P}{4\pi \epsilon_0r^2}\), where r is the distance of any axial point, situated at 2 m from the centre of the dipole.

Vernalisation
The term "vernalization" comes from the Latin word "vernus," which simply means "spring." It directly means "to make spring-like." Vernalisation is described as a plant's qualitative or quantitative dependency on subjection to low temperatures to blossom. Metabolic activities, flowering, and seed germination in plants are all pompoused by temperature.
Types of Vernalisation:
Vernalisation can be classified into the following types:
- Obligate Vernalisation: Plants must be exposed to lower temperatures for a set amount of time. For instance, Cabbage.
- Facultative Vernalisation: Flowering takes place earlier in plants when they are exposed to lower temperatures. For instance, Annual winter triticale.
