dna replication Flashcards
1
Q
deoxyribose sugar, nitrogen base, phosphate
A
building blocks of DNA polynucleotide
2
Q
what direction does DNA replication proceed?
A
5’ to 3’
3
Q
leading strand
A
DNA is replicated in one smooth, continuous process
4
Q
lagging strand
A
DNA is replicated in small sections then fused together
5
Q
helicase
A
seperates the DNA strands, requires ATP
6
Q
okazaki fragments
A
short sections of primer RNA and DNA that form on the lagging strand. will be joined together later.
7
Q
ligase
A
healing enzyme, holds fragments
8
Q
what serves as substrates in DNA synthesis
A
deoxyribonucleotide triphosphates w2
9
Q
dna polymerase
A
enzyme that is responsible for replicating and forming new copies of DNA
10
Q
