Answer 1
Answer:

Explanation:

When a farmer measures the depth of the soil to measure the saturation point of water in the soil and found that after 1.2 inches the soil is wet but after a week the saturated soil is found at 1.6 inches. There could be many reasons for this:

1. The crops could have utilized the water present in the topsoil.

2. The water has been evaporated from the soil due to farming practices if performed in that week.

3. The water could have percolated down as the soil could be highly porous.

4. The saturation of water depends on the physicochemical factors of soil also.

What enzyme unwinds or unzips the parent strand?

Answers

The enzyme that unwinds or unzips the parent strand is called helicase. Helicase is a type of protein that is found in all cells.

What is the role of helicase?

Helicase is responsible for unwinding the double helix structure of DNA. Helicase works by binding to the DNA double helix and then using its energy to break the hydrogen bonds that hold the two strands together. This causes the strands to separate, or unzip.

Once the strands are separated, helicase moves along the DNA, unwinding it as it goes. This allows other enzymes to access the DNA and start the process of DNA replication.
