DNA Replication

Question 1

What is the type of DNA Replication that occurs…

Answer 1

Semi-conservative replication

Question 2

DNA template

Answer 2

What will be copied

Question 3

Free nucleotide

Answer 3

To synthesise a new strand

Question 4

DNA helicase

Answer 4

Enzymes to break apart the strand

Question 5

Polymerase

Answer 5

Enzyme to re-synthesise the back-bone

Question 6

Stages of semi-conservative DNA replication

Answer 6

1. DNA helicase breaks apart the 2 parent strands
2. The DNA strands move apart and act as template strands
3. Free nucleotides in the nucleoplasm line up with their complimentary base pair
4. Hydrogen bonds reform
5. DNA polymerase catalyses the polymerisation of the polynucleotide chain (polydiester bonds)
6. Two new DNA molecules are formed, each with half of the original parental DNA
