replication of DNA Flashcards
1
Q
what is the purpose of DNA replication?
A
so when cell division occurs the daughter cell inherits an identical copy of DNA
2
Q
what are the requirements for DNA replication?
A
DNA template, nucleotides, DNA polymerase, primers
3
Q
what is PCR`?
A
a technique used to amplify DNA in vitro
4
Q
what is DNA polymerase?
A
an enzyme that adds new nucleotides to a growing strand of DNA.
5
Q
what is a primer?
A
short strands of nucleotides which binds to the 3’ of DNA to allow DNA polymerase to add nucleotides
6
Q
why is the lagging strand synthesised in fragments?
A
because nucleotides cannot be added 5’ end because DNA polymerase can only add DNA nucleotides in a 5’ to 3’ direction.
