DNA replication

• What type of replication does DNA undergo to ensure genetic continuity?

  Semi-conservative replication
• Why is semi-conservative replication important for cells?

  It ensures genetic information is passed on
• What are the steps of semi-conservative replication of DNA?

  1. DNA helicase separates the strands
  2. Complementary base pairing occurs
  3. DNA polymerase forms phosphodiester bonds
• What enzyme causes the two strands of DNA to separate?

  DNA helicase
• What does DNA helicase break to separate the DNA strands?

  Hydrogen bonds between complementary bases
• What occurs between the template strand and free nucleotides during replication?

  Complementary base pairing
• What enzyme joins activated nucleotides together during DNA replication?

  DNA polymerase
• What type of bonds does DNA polymerase form to join nucleotides?

  Phosphodiester bonds
• What is the result of the semi-conservative replication process?

  Two identical strands of DNA are formed
