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]

• Guanine [G]

• Cytosine [C]

• Thymine [T]

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]
