DNA and Heredity Flashcards
1
Q
What are the proteins involved in DNA replication?
A
DNA helicase, Single-strand binding proteins, DNA polymerases, DNA primase, DNA ligase.
2
Q
DNA helicase
A
Uses the energy from ATP hydrolysis to unwind DNA
3
Q
Single-strand binding proteins
A
Prevents single strands from binding again
4
Q
DNA polymerase
A
Makes new DNA; odd nucleosides
5
Q
DNA primase
A
odd, required primer; made of RNA
6
Q
DNA ligase
A
Seals any gaps in the DNA
7
Q
What are the steps in DNA replication
A
Initiation, Elongation, and Termination
8
Q
Initiation
A
double helix is unwound, making two template strands
9
Q
Elongation
A
addition of complementary base pairs linked by phosphodiester bonds
10
Q
Termination
A
DNA synthesis ends when all DNA regions have been replicated
