Answer:
<h2>C. What is the length of the S phase of the cell cycle?
</h2>
Explanation:
- Such type of technique that is used to tack or identified the passage or location of the metabolic reaction, organelles and some other during the research or experiment is known as radiolabelling.
- During the study of the synthesis of the DNA, the nucleotides are labeled to check the S phase of the cell cycle.
- Since the synthesis of the DNA takes place during this phase so the time and length of the S phase can be easily obtained during the experiment.
- This technique is also used for different purposes during the biomolecular experiment and some other disciplines.
Answer:
The correct answer will be option-C
Explanation:
LUCA or the last universal common ancestor or the concestor represents one of the populations of the most common ancestor of all the organisms present on this Earth today.
The LUCA organisms are not considered the first form of life on earth but studies show that they spread their genes to all other organisms through horizontal transfer methods.
Recent studies by William F. Martin indicates that LUCA was anaerobic thermophilic, H₂-dependent, CO₂-fixing organisms, therefore, the correct answer is option-C.
D. Neon is the most stable element because its highest occupied energy level is filled.
