Semi conservative DNA replication model answer
(5)
Helicase breaks hydrogen bonds between the 2 DNA template strands
Free floating DNA nucleotides are attracted to complimentary exposed DNA nucleotides on the template strands
Adenine pairs with thymine
Cytosine pairs with guanine
DNA polymerase joins adjacent DNA nucleotides in the newly synthesised strand
by a condensation reaction that forms phosphodiester bonds between DNA nucleotides in the newly synthesised strands
What is the function of helicase in DNA replication?
breaks hydrogen bonds between the 2 dna template strands
In what part of the cell cycle is DNA replicated ?
interphase
What is the function of DNA polymerase in replication?
to catalyse condensation reactions between adjacent dna nucleotides forming phosphodiester bonds in the newly synthesised strands
What is meant by semi conservative replication?
The DNA strands produced contain one parent strand and one daughter strand in their double helix
