DNA Replication Flashcards
1
Q
Helicase unwinds part of the DNA Helix
A
True
2
Q
SSBP
A
Single Stranded Binding Proteins
3
Q
Gyrase
A
prevents tangling upstream from the replication fork
4
Q
Summary Pt. 1
- Helicase
- SSBP
- Gyrase
A
The helicase unwinds part of the DNA helix which the SSBP stabilizes and prevents from closing. Then, the DA gyrase will stop tangling upstream from the replication fork
5
Q
Primase
A
Primer, single strand of DNA
6
Q
DNA polymerase
A
Builds new DNA strand, can only add nucleotides to existing stands of DNA
7
Q
Summary Pt. 2
- Primase
- DNA polymerase
A
The primase will prime a single strand of DNA so the DNA polymerase can add nucleotides to the existing strands of DNA
8
Q
Ligase
A
Glue
9
Q
Summary Pt. 3
- Ligase
A
The daughter DNA strand is built and a new complementary base is added because of DNA polymerase. The ligase “glues” them together.
