DNA Replication Flashcards
1
Q
DNA Helicase
A
Emzyme that breaks down hydrogen bonds between bases
2
Q
Single Stranded Binding Proteins
A
Keeps DNA from coming back together
3
Q
DNA Polymerase
A
Makes a complementary strand of DNA in the 5-3 direction
4
Q
DNA Ligase
A
“Glue” that forms the bond between the fragments to form one continous strand of DNA
5
Q
RNA Primase (Primers)
A
Starting point to begin DNA. The point that the DNA Polymerase builds off of
6
Q
Leading Strand
A
Continuous strand of DNA that is made in the direction of the replication fork. 5 to 3
7
Q
Lagging strand
A
DNA strand that is repilcated in small fragments, called Okazaki fragments, in the opposite direction of the replication fork
8
Q
Purines V.S. Pyrimidines
A
Adenine (purine) - Thymine (pyrimidine)
Guanine - Cytosine
