DNA FACTS
established by James Watso
n and Francis
Crick
Shape of a double helixSlide5
codes for your genes (traits)
made of repeating subunits called
nucleotidesSlide6
What is a nucleotide?
Has three parts:
PHOSPHATE
DEOXYRIBOSE (sugar)
BASE (A,T,G,C)Slide7
Base-Pair Rule
Adenine <==> Thymine
Guanine <==> Cytosine
The sides of the DNA ladder are
phosphate
&
sugar
held together by
hydrogen bondsSlide8
Base Pair Rule
One side: A T A T C A T G C G G G
Other side:Slide9Slide10
DNASlide11
How the Code Works
The combination of A,T,G,C determines what traits you might have.....
C A T C A T = purple hair
T A C T A C = yellow hairSlide12
Think of the bases of DNA like letters.
Letters form words....(amino acids)
Words form sentences...
.
(genes)
*endless
