The process begins when an enzyme called helicase unwinds the double helix DNA molecule. This opens the DNA strands, allowing other enzymes to match the exposed nucleotides, creating two identical strands of DNA. The conservative model proposes that the original strand is completely replicated. However, the semiconservative model suggests that new DNA molecules are formed by the combination of old and new nucleotides.
DNA replication involves the unwinding of the double helix, allowing the exposed nucleotides to be matched by RNA polymerase, creating a complementary RNA-strand.
In the semiconservative model, the original DNA molecule is conserved in both new DNA strands. In the conservative model, the original molecule is completely replicated.
The conservative model proposes that the original DNA molecule is completely replicated, while the semiconservative model suggests that new DNA molecules are formed from a combination of old and new nucleotides.
