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.

If carbon dioxide is needed photosynthesis and water is plentiful, which of the following is likely to occur? A. Additional water will be gained and the plant cells will become rigid. B. The stomata will open until too much water is lost. C. Water pressure is going to decease in the guard cells. D. The stomata will close until enough water is lost.

Answers

Remember, if CO2 (which is a gas) is needed, then the stomata must open up to let in air. This limits your answers to A and C. If you have plenty of water, how would too much water be lost? I think you can figure out the answer from that.Let me know if this is clear and helps or not.
A : Additional water will be gained and the plant cells will become rigid 
B : The stomata will open until too much water is lost 
C : Water pressure is going to decease in the guard cells 
D : The stomata will close until enough water is lost 

The answer D : The stomata will close until enough water is lost 

Which statement best describes the human immunodeficiency virus (HIV) that has been shown to cause AIDS in humans?

Answers

The first stage of HIV infection is known as the acute stage. The body responds by producing HIV antibodies and killer T- cells which are special lymphocytes that seek out and destroy invading pathogens such as viruses and bacteria. Two to four weeks after infection, the immune system launches an attack against HIV using these antibodies and killer T-cells, significantly reducing HIV level on blood. A percentage of the viruses however escapes this onslaught by hiding in other cells and continue to multiply.
