Transcript of DNA Structure/function and history

Who/How was it discovered?
Watson and Crick
DNA Structure
DNA FUNCTION
1. DNA is the code to make proteins.
DNA- So complex its simple
D
eoxyribose
N
ucleic
A
cid

SUGAR
Genetic Material
Rosalind Franklin
Made the first model
of DNA structure
Crystalline Structure
of DNA
Xray Diffraction

Adenine
Thymine
Cytosine
Guanine
Pyrimidines
Purines
2. DNA regulates what Protein is made by the cell and when.
3. DNA determines Cell Differentiation
Replication
- DNA copies its self
Transcription
-

makes a RNA
copy of 1 gene
Translation-
RNA is translated
into Protein
Objective- students will know the basic structure and function of DNA and the scientists who discovered it.
DNA/ Chromosome Structure
DNA is wrapped around the Protein Histone To produce the tightly packed chromosome.
Made up of a chain of nucleotides
1 Sugar (deoxiribose)
1 Phospate
1 Nitrogen Base (A,T,C,G)
The Nitrogen bases always pair the same way.
