1
Q
nucleotides are the building blocks of..
A
DNA. 5 carbon, and phosphate group
2
Q
enzymes,
A
DNA polymerase, helicase, primase, and ligase
3
Q
helicase
A
unzipping DNA, breaks though hydrogen bonds that hold them together
4
Q
dna polymerase
A
builder, replicates to build new strand of DNA
5
Q
primase
A
initializer, makes primer so primase knows where to start
6
Q
ligase
A
glues DNA segments together
7
Q
step 1:
A
helicase unzips DNA
8
Q
step 2:
A
Single stranded binding proteins bind to keep DNA separate
9
Q
step 3
A
topoisomerase keeps DNA from super coiling
10
Q
step 4
A
primase makes DNA primers on both strands
11
Q
how do the strands lie?
A
anti-parallel, because it has to go five prime to three prime
12
Q
semi constructive
A
copy of DNA that has one old strand and one new strand
