Nucleotide
The building block for all nucleic acids
Complementary base pairing
Cytosine to Guanine, and Thymine to Adenine
How many hydrogen bonds Thymine to Adenine form.
2

3
Which bases are part of Purine
Adenine and Guanine

5’ to 3’ directions
The orientation of a nucleic acid strand (DNA or RNA) based on the carbon numbering in the sugar ring.
Anti-Parellel Configuration
Two complementary strands of the double helix running in opposite directions, with one strand oriented in a 5′ to 3′ direction and the other in a 3′ to 5′ direction.
Three Components of DNA replication
Copy of Original DNA, Copying Enzyme, New bases
Semi-discontinuous
Three phases of DNA Replication
Initiation, Elongation, Termination
Enzymes involved in Initiation
Helicase, SSBP (Single Strand Binding Proteins)
Enzymes involved in Elongation
Primase, DNA Polymerase
Enzymes involved in Termination
DNA ligase, Telomerase
Okazaki Fragments
