Question

The enzyme that breaks H₂ bonds in DNA is
A. Helicase
B. Topoisomerase
C. Ligase
D. Polymerase

Answer 1

Hint:
Before we proceed into the problem, it is important to know the definition of Enzymes in DNA.
Enzymes are proteins that play an important role in DNA replication and transcription. They participate in the chemical reactions that control how genes are expressed, which helps to keep your cells healthy and functioning correctly.

Complete step by step solution:
Enzyme activity is regulated by enzymes themselves or by their inhibitors, which means that the level of enzyme activity can be controlled. This is why it's often important to maintain a balance between enzyme production and inhibition so that all critical tasks within the cell are carried out effectively.
DNA is a long molecule that contains the genetic information of an organism. The DNA polymerase enzyme plays a key role in mitochondrial replication, which is the process by which new cells are created in the body. This enzyme works to break down H₂ bonds in DNA so that it can be copied and passed on to future generations.
It is a crucial enzyme in DNA replication and is in charge of "unzipping" the double helix shape by severing the hydrogen bonds between the bases on the opposing DNA strands.
Therefore, the enzyme that breaks H₂ bonds in DNA is Helicase.

Option ‘A’ is correct

Note:
Helicase is an enzyme that helps to break down proteins. This process is called protein digestion and it's crucial for the body to function properly. Helicase enzymes are found in a number of important organs, including the stomach, small intestine, and colon. They are also present in pancreatic cells and play a role in the production of glucose.
