used phages to find out DNA is the heridity molecule
Chargauff’s rule
found DNA structure
DNA replication
production of exact copies of DNA with identical base sequences
semi-conservative
half of the old DNA gets replicated
Helicase
unzips the DNA

help hold single strands apart
gyrase
relaxes the supercoil
DNA primase
primer of DNA, puts little blocks in
DNA polymerase 3
binds together complimentary nucleotides
DNA polymerase 1
removes primer and fills in the gaps with nucleotides
DNA ligase
join/glue last fragments together
