What is the name for the basic units which make up strands of DNA?
Phosphates
Nucleotides
RNAs
What are the DNA base pairing rules?
Adenine to Guanine, Cytosine to Thymine
Adenine to Cytosine, Thymine to Guanine
Adenine to Thymine, Cytosine to Guanine
PCR is a technique used for what?
The amplification of DNA in vitro
The amplification of DNA in vivo
Sequencing the nucleotide bases of DNA
What are primers?
Single stranded random sequences of nucleotides
Single stranded sequences of nucleotides which are complementary to a target sequence
Double stranded sequences of nucleotides which are complementary to a target sequence
Why can both strands of DNA not be replicated continuously?
DNA nucleotides can only be added continuously in a 5’ to 3’ direction
The DNA polymerase can only act on one strand at a time
There is not enough space for both strands to be copied
