Semi conservative replication Flashcards
1
Q
whats the first stage (on prev flashcards)
A
the enzyme helicase breaks the hydrogen bonds between the polynucliotide strands so the helix unwinds
2
Q
what do the bases from the origional strand do
A
tey act as a template and the nucliotides attach to their complimentary base pairings
3
Q
what does semi mean and how is it related to this
A
semi- half
it half of the origional dna
4
Q
what reaction joins the nucleotide and the new strands together. what bonds are formed
A
Condensation
hydrogen bonds are formed
5
Q
what is this catalysed by
A
DNA Polymerase
6
Q
how are each of the strands antiparallel
A
each end of the dna strands in slighly different.
so the active site of dna polmerase is only complimentary to 3’ of newly formed strand
