before cells divide, what must the DNA do?

all DNA must replicate to provide a copy for the new cell

2
New cards

what’s the process of DNA replication?

semi conservative

3
New cards

what does semi conservative mean?

in the daughter DNA one strand is from the parental DNA and one strand is newly synthesised

4
New cards

what happens during stage one of DNA replication?

  • DNA helicase breaks the hydrogen bonds between the complimentary base pairs between the two strands within a double helix

  • this causes the DNA double helix to unwind


5
New cards

what happens during stage two of DNA replication?

  • each of the separated DNA strands acts as a template

  • free floating DNA nucleotides within the nucleus are attached to their complementary base pairs on either template strands of the parental DNA


6
New cards

what happens during stage three of DNA replication?

  • the adjacent nucleotides are joined together (to form the phosphodiester bond) by a condensation reaction

  • DNA polymerase catalyses the joining together of adjacent nucleotides


7
New cards

what happens during stage four of DNA replication?

  • the two sets of daughter DNA contains one strand of the parental DNA and one newly synthesised strand
