Detailed explanation-1: -Helicases are enzymes that bind and may even remodel nucleic acid or nucleic acid protein complexes. There are DNA and RNA helicases. DNA helicases are essential during DNA replication because they separate double-stranded DNA into single strands allowing each strand to be copied.
Detailed explanation-2: -The first step in DNA replication is to ‘unzip’ the double helix structure of the DNA? molecule. This is carried out by an enzyme? called helicase which breaks the hydrogen bonds? holding the complementary? bases? of DNA together (A with T, C with G).
Detailed explanation-3: -Helicases are enzymes that use ATP-driven motor force to unwind double-stranded DNA or RNA.
Detailed explanation-4: -DNA replication begins when an enzyme called helicase unwinds, and unzips the DNA molecule.
