DNA Replication Flashcards
1
Q
DNA Gyrase…
A
Relaxes and uncoils the DNA moleucle
2
Q
DNA Helicase…
A
Breaks the weak hydrogen bonds that hold the two DNA strands together
3
Q
DNA Ligase…
A
Seals the gaps between nucleotides along the sugar-phosphate backbone
4
Q
DNA polymerase 1…
A
Replaces the RNA primer with proper DNA nucleotides
5
Q
DNA polymerase 2…
A
Proof reads the finished molecule; corrects mistakes
6
Q
DNA polymerase 3…
A
Adds the majority of free-floating nucleotides along the newly formed strands.
7
Q
RNA primase…
A
Adds an RNA primer
8
Q
Semi-conservative replication is…
A
Semi-conservative replication is how DNA copies itself. Each new DNA strand is made of one old strand and one new strand. This helps pass on accurate genetic information.
