Polymerase helps to copy and make new strands of DNA.
Polymerase is an enzyme that plays a crucial role in DNA replication. It works by attaching to a DNA strand and reading its sequence. It then helps in adding new nucleotides to create a complementary copy of the DNA strand. As DNA replication proceeds, polymerase continuously moves along the DNA helix, unwinding it and synthesizing a new strand. This process ensures the accurate duplication of genetic information.
