DNA replication begins with helicase unwinding the helix, then each strand serves as a template for new nucleotides to bind via hydrogen bonds, and DNA polymerase forms phosphodiester bonds to create the new sugar-phosphate backbone.
- DNA helicase breaks H bonds, unwinding helix <b>- Each DNA strand used as a template for a new strand<br></b> - Free DNA nucleotides align with complementary base, form H bonds - adenine forms 2 H bonds with thymine, cytosine forms 3 H bonds with guanine - DNA polymerase forms phosphodiester bonds between nucleotides - by condensation reactions - forms sugar-phosphate backbone - continues along DNA molecule
