1 of 12
How does a nucleotide form?
Condensation reactions to make a nucleotide, form dinucleotides, form polynucleotides

What do we call the DNA structure?
Double helix structure
3 of 12
What is the function of DNA?
Responsible for passing down genetic information
4 of 12
What are the four adaptations of DNA?
Stable to pass down without change, helical structure for protection from chemicals, joined by hydrogen bonds only for easy separation during replication, large molecule for lots of genetic information
