Detailed explanation-1: -Helicase. Helicase is the enzyme, which unzips the DNA strands by breaking the hydrogen bonds between them. Thus, it helps in the formation of the replication fork.
Detailed explanation-2: -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-3: -The separation of the duplex DNA results in formation of the replication fork. The studies showed that two DNA helicases start the replication.
Detailed explanation-4: -DNA replication is the process whereby a molecule of DNA is copied to form two identical molecules. First, an enzyme called a DNA helicase separates the two strands of the DNA double helix. This forms a structure called a replication fork that has two exposed single strands.
Detailed explanation-5: -DNA helicase is an enzyme that unwinds the DNA double helix by breaking the hydrogen bonds between the complementary bases.
