2.3.2 Nucleotides and Nucleic Acids DNA Replication Flashcards
1
Q
DNA Replication is Semi-Conservative, What does this mean?
A
The product of replication consists of one new DNA strand and one Old DNA strand.
2
Q
What are the four enzymes of DNA replication and their functions?
A
DNA Gyrase - unwinds double helix
DNA Helicase - unzips (breaks Hydrogen bonds between DNA strands)
DNA Polymerase - Adds free nucleotides using complementary base pairing
DNA Ligase - Joins DNA together
3
Q
What is a template strand?
A
A strand of DNA that is used for complementary base pairing with free nucleotides
4
Q
Where are the free nucleotides found?
A
In ribosomes
5
Q
Where does DNA replication occur?
A
Eukaroytic cells - Nucleius
Prokaryotic cells - Nucleoid region
