Question 1 of 5
1. Question
A recent study on rice plants revealed a surprising ability to adapt to cold through non-genetic means. Consider the following statements:
- The gene ACT1 in rice is responsible for producing a protein that helps the plant tolerate cold temperatures.
- The adaptation was made possible through an epigenetic modification, not by a change in the DNA sequence.
- These epigenetic changes were found to be heritable for at least five generations.
- The study supports the classical Darwinian model of evolution based solely on natural selection.
Which of the statements given above is/are correct?
Correct
Correct Answer: A. 1, 2 and 3 only
Explanation:
- Statement 1 is correct: ACT1 gene helps rice plants survive in the cold by producing a protective protein.
- Statement 2 is correct: The adaptation was triggered by an epigenetic tag, not a mutation in the DNA sequence.
- Statement 3 is correct: The change persisted across five generations even without the cold exposure.
Statement 4 is incorrect: The study challenges the classical Darwinian model and gives credence to Lamarckian inheritance.
Incorrect
Correct Answer: A. 1, 2 and 3 only
Explanation:
- Statement 1 is correct: ACT1 gene helps rice plants survive in the cold by producing a protective protein.
- Statement 2 is correct: The adaptation was triggered by an epigenetic tag, not a mutation in the DNA sequence.

4. Question
Which of the following pairs of radar types and their applications are correctly matched?
- Synthetic Aperture Radar (SAR) – High-resolution Earth imaging through clouds
- Doppler Radar – Speed detection using frequency shift
- Phased Array Radar – Imaging of planetary surfaces
- Over-the-Horizon Radar (OTH) – Detection of targets beyond line of sight

Correct
Answer: A. 1, 2 and 4 only
Explanation:
