what is DNA ligase
an enzyme that seals the gaps between the okazaki fragments on the lagging strand
double helix

how many bonds between G and C
3
how many rings to pyramidines have
1
name the nitrogeneous bases
adenine, thymine, cytosine, guanine
what is primase
an enzyme that synthesizes short RNA primers needed to start DNA replication
A-T and C-G
where does the phospate group bind to the sugar
on the 5 prime side of the carbon
what is semiconservative replication
Each molecule consists of one original parental strand and one newly synthesized strand because half of the original DNA molecule is conserved in each of the two daughter DNA molecules.
whats the bond that holds nitrogeneous bases called?
hydrogen bonds
what is topoisomerase
an enzyme that relieves tension caused by unwinding
where is DNA located
nucleus
where does the nitrogenous base bind to the sugar
on the 3 prime side

continuous (leading strand)
