A double helix is
made up of 2 strands of DNA
The 4 DNA bases are
Guanine, Cytosine, Adenine, Thymine
Adenine pairs with
Guanine pairs with
Deoxyribose sugar can be found at the

What enzyme adds the complementary nucleotides during replication?
What end can nucleotides be added to?
The 3' end
Why is DNA initially heated to 92-98oC during PCR?
To break the hydrogen bonds and separate the strands
What doe PCR make?
Amplified copies of DNA
During PCR, What temperature is the DNA cooled to and why?
It is cooled to 50-65oC to allow primers to bind
