The enzyme DNA polymerase is responsible for linking the nucleotides in a new DNA strand.
Before replication of DNA occurs, the DNA double helix is first unwound, after which the two strands must be separated much like the two sides of a zipper by breaking the weak hydrogen bonds that link the paired bases.
The unwound DNA strands are held apart to expose the bases so that new nucleotide partner can hydrogen-bond to them. It is DNA polymerase that moves along the exposed strand, joining newly arrived nucleotides into a new DNA strand by linking paired bases by hydrogen bonds.
The DNA polymerase is responsible for facilitating the hydrogen bonds between nucleotides in a new DNA molecule.
its the polymerase
"DNA polymerase" is responsible for facilitating the hydrogen bonding between the nucleotides in a new DNA molecule.
It is an enzyme which helps in synthesis of the DNA molecules from the deoxyribonucleotides, which is considered as the base of the DNA. The enzyme s very much required for the replication of the DNA and they have been seen working in pairs so that similar strands of the DNA can be created from the single DNA molecule. DNA polymerase helps in formation of the copies of the DNA which is in form of the nucleic acid molecules.
