200
What is the name of 2
DNA helicase
300
Rosalind
Using x-rays
Either x-ray diffraction
X-ray crystallography
Cam up with the technique to see what DNA looks like
300
DNA helicase
unwinds DNA
300

Chagaff
Known for portions
A and T have to have the same percent
C and G have to have the same percent
Have to add up to 100%
400
Topoisomerase II
Relieve any tension on the DNA strand as it unwinds
400
DNA polymerase I
removes primers to allow DNA nucleotides to be attached
400
Identify the three parts of a nucleotide
1. phosphate groups
2. sugar
3. nitrogenous base
400
What is the name of 6
DNA polymerase III
500
Griffiths and Avery
Worked with mice and bacteria
One was pathogenic and nonpathogenic
Certain cells can pass off the DNA
500
RNA Primase
creates primers so DNA polymerase III knows where to attach
