2
Q
AT has how many H bonds
A
2
3
Q
helicase
A
breaks H bonds
4
Q
topoisomerase
A
prevents super coiling
-separates backbone (posphodiester bond)
5
Q
5-3
A
direction for nucleic acids
6
Q
N to C
A
proteins
7
Q
ligase
A
enzymes that bring stuff together
form new bonds - phosphodiester bonds
8
Q
single stranded binding protein
A
stops your DNA from renealing
9
Q
what are some organisms where they don’t need single stranded binding proteins
A
archaes
because they live in such high temp environments
ex: taq
10
Q
telomere
A
prevents losing genetic info
repetitive nucleoside sequence at the very end
11
Q
work fragments okazaki how is this
A
this is how okazaki fragments work
same way and same sequence, just backwords
12
Q
endonuclease
A
remove the damaged DNA
- also known as restriction enzymes (common target sites are palindormes)
- cuts phosphodiester bonds
13
Q
palidromes
A
racecar
