Answer:
The correct answer is option A. "They only introduce supercoiling and cannot relax a covalently closed circular DNA".
Explanation:
Type II topoisomerases are enzymes that regulate the winding an unwinding of DNA during DNA replication. Basically, these enzymes are the scissor that remove the knots and tangles formed during the replication process. Is false to affirm that type II topoisomerases only introduce supercoiling and cannot relax a covalently closed circular DNA. Bacterial type II DNA topoisomerases work with the circular DNA of bacterium by changing the linking number of circular DNA by ±2.
Answer:
Plants produce oxygen gas and glucose molecule during the process of photosynthesis by absorbing radiation of the sun.
Explanation:
Photosynthesis is a process in which glucose and oxygen are produced by the combination of carbondioxide and water in the presence of sunlight. Carbondioxode is taken in the leaves through stomata and water is absorbed by the plant from the soil. When these two substances combine in the presence of sunlight produces glucose and oxygen.
