Web5 de mar. de 2024 · DNA replication begins when an enzyme, DNA helicase, breaks the bonds between complementary bases in DNA (see Figure below). This exposes the bases inside the molecule so they can be “read” by another enzyme, DNA polymerase, and used to build two new DNA strands with complementary bases, also by DNA polymerase. Web2 de abr. de 2024 · This process is called replication. Given the complementary double strands of DNA, it is relatively easy to see how DNA as a molecule is well structured for …
