DNA replication

• What is semi-conservative replication?

  • When an original DNA strand joins with a new DNA strand
• What is the process of semi-conservative replication?

  • DNA helicase breaks H bonds between complementary base pairs, unwinding the double helix
  • Free flowing complimentary nucleotides join to the original template strand
  • DNA polymerase joins the nucleotides together by phosphodiester bonds
• Whats the evidence for semi-conservate replication?

  • Meleson and stahl proved semi conservative replication by using Nitrogen 14 free nucleotides and Nitrogen 15 DNA
• Whats the evidence for DNA structure?

  • Watson and crick
• Why was semi-conservative replication doubted?

  • Because it was too simple
