How many "sides" does DNA have?
What is DNA replication?
The copying of DNA during S phase of interphase.
Where does DNA replication occur?

How many sides are used as a template during DNA Replication?
Both (2) sides are used to replicate DNA.
What is transcription?
Using DNA as a template to make RNA.
Where does transcription occur?
How many sides of DNA are used as a template during transcription?
Only 1, the active side.
What is a codon?
A codon is a sequence of 3 mRNA nucleotides that code for a particular amino acid.
What types of RNA are involved in translation?
What is a purine?
A nitrogen base with a double ring shape.
What is a pyrimidine?

What is found in a DNA nucleotide?
PhosphateDeoxyribose (sugar)Nitrogen base (A,T,G, or C)
What is a base pair?
A base pair is is two complimentary nucleotides held together by a weak hydrogen bond between the bases.
Where are anticodons found?
What is the job of mRNA?
mRNA is a readable version of DNA's instructions used by ribosomes to make proteins.
