Deoxyribonucleic Acid
DNA
DNA…• … is the blueprints or instructions for all living things.
• … has the same basic structure for all living things
• … belongs to a group of complex molecules known as Nucleic Acids.
All nucleic acids including DNA are composed of Nucleotides
•Nucleotides
What DNA is made of?
Nucleotides
• There are four different kinds of bases– Adenine– Thymine– Guanine– Cytosine
Nucleotides• Nucleotides combine to form DNA chains
A to T, C to G rule
• Adenine always combines with Thymine
A-T• Guanine always combines with
Cytosine
C-G
