WebDec 3, 2024 · DNA replication is a process by which DNA replicates by a semi-conservative method. The DNA double helix unwinds from the place where replication has to occur. Each strand of the DNA serves as a template strand for producing a daughter strand. The DNA polymerase adds nucleotides complementary to each parent strand. WebRNA polymerase unwinds/"unzips" the DNA by breaking the hydrogen bonds between complementary nucleotides. RNA nucleotides are paired with complementary DNA bases. ...
