Detailed explanation-1: -DNA helicases are molecular motors. Through conformational changes caused by ATP hydrolysis and binding, they move along the template double helix, break the hydrogen bonds between the two strands and separate the template chains, so that the genetic information can be accessed.
Detailed explanation-2: -Hydrogen bonds in DNA replication are broken down by the helicase class of enzymes. This causes the double-stranded DNA molecule to unzip into two single strands, allowing each strand to be replicated.
Detailed explanation-3: -Key enzyme involved in DNA replication, it is responsible for ‘unzipping’ the double helix structure by breaking the hydrogen bonds between bases on opposite strands of the DNA molecule.
Detailed explanation-4: -The main function of DNA helicase is to separate two strands of DNA for replication. Helicase is the enzyme, which unzips the DNA strands by breaking the hydrogen bonds between them.
Detailed explanation-5: -Answer: Gyrase breaks the phosphodiester linkages in the DNA backbone, while helicase disrupts the hydrogen bonds between the paired bases of antiparallel strands.
