Enzymes
what enzyme builds a complimentary new strand of DNA that base pairs with the parent strand
Dna Polymerase
DNA Poly inserts complementary nucleotides from this end to this end
5'-3'
Link the base pairs (A,T,G,C)
A-T, G-C
what enzyme can replicate 749 nucleotides per second
DNA polymerase
what enzyme is involved with the first step of DNA replication
what enzyme separates strands of DNA by breaking hydrogen bonds between base pairs
helicase
this strand is synthesized by adding nucleotides to the 3' end
Leading strand
which 2 bases are double ring structures?
Guanine, Adenine
what type of energy does helicase use to break bonds?
ATP
what is the second step of DNA replication
Primer Binding
what enzyme builds an RNA primer that is required to recruit DNA polymerase to replication bubble
primase
this strand is the daughter DNA that is synthesized discontinuously in DNA replication
Lagging strand
Which 2 bases are single ring structures
Cytosine, Thymine
what is the 3rd step of DNA replication
Elongation-creating the new strand
what enzyme joins together the backbone of Okazaki fragments
ligase
what is the 4th step of DNA replication
termination: ligase joins Okazaki fragments together forming a single unified strand
This enzymes lengthens DNA and can be found in cancer cells
Telomerase
