DNA

The Blueprint of Life"

DeoxyriboNucleic Acid
established by James Watson and Francis Crick
•Shape of a double helix

Genes

•codes for your genes (traits)
•made of repeating subunits called nucleotides

Base-Pair Rule

Adenine <==> Thymine
Guanine <==> Cytosine
The sides of the DNA ladder are phosphate & sugar
held together by hydrogen bonds

Multiple Choice

How the Code Works

The combination of A,T,G,C determines what traits you might have, for ex.
C A T C A T = purple hair
T A C T A C = yellow hair
