Name the enzyme that breaks the hydrogen bonds holding the two DNA strands together during DNA replication?

DNA helicase is the enzyme that breaks the hydrogen bonds which holds the two DNA strands together during DNA replication.

During replication of DNA , the enzyme DNA helicase separates the two strands of DNA and causes the breakdown of hydrogen bonds between the two DNA strands which leads to separating of the DNA double helix into two individual strands which make easier to copy it.

In conclusion, DNA helicase is the enzyme that breaks the hydrogen bonds.
