3. 1. 5. 2 DNA Replication

Question 1

What does semi-conservative replication ensure?

Answer 1

The semi-conservative replication of DNA ensures genetic continuity between generations of cells.

Question 2

What is the process of semi-conservative replication of DNA?

Answer 2

• Unwinding double helix
• breakage of hydrogen bonds between complimentary bases in the polynucleotide strands
• the role of DNA helicase in unwinding DNA and breaking its hydrogen bonds
• Attraction of new DNA nucleotides to exposed bases on template strands and base pairing
• The role of DNA polymerase in the condensation reaction that joins adjacent nucleotides
