Components of DNA
DNA is a nucleic acid made up of __________ joined into long
strands or chains by __________ bonds.
Nucleotides are made of what 3 components?
• 5-carbon sugar
• Phosphate group
• Nitrogenous base = bases that
contain nitrogen
Nucleotides
Covalent
Components of DNA
What are the four kinds of nitrogenous bases within DNA?
• Adenine [A]

Analyzing Data
Read Chargaff’s Rule (pg. 345) then complete Analyzing Data:
Base Percentages
1. Interpret Tables - Which organism has the highest
percentage of adenine?
2. Calculate - If a species has 35% adenine in its DNA, what is
the percentage of the other three bases?
3. Draw Conclusion - What did the fact that A & T, and G & C,
occurred in equal amounts suggest about the relationship
among these bases?
Double Helix
Antiparallel Strands
• Bases can line up.
• Hydrogen bonds can form
between base pairs.
p. 347-348
Double Helix
Hydrogen Bonding
Base Pairing
• [A] = [T]
• [G] = [C]
