Transcript of Structure of DNA

Structure of DNA and RNA
By Mrs. Alcorn
Structure of DNA: Discovered in 1953.
Watson and Crick
They used Rosalind Franklin's data as a basis for their model.
A Little History...
DNA is found in all living things.
DNA contains instructions for making a complete organism.
DNA is shaped like a twisted ladder.
Aka "Double Helix"
DNA Diagram:
Three parts of a nucleotide:
1. Phosphate group
2. Deoxyribose (5 Carbon Sugar)
3. Nitrogenous Bases
4 Nitrogenous Bases:
The bases form the "steps" of the ladder.

Chargaff Base Pairing Rules:
Adenine always pairs with thymine.
Cytosine always pairs with guanine.
RNA: ribonucleic acid
Single stranded.
Contains uracil ("U") instead of thymine ("T").
Three types of RNA:
mRNA:
messanger
tRNA:
transfer
rRNA:
ribosomal
DNA: Deoxyribonucleic acid!
Nucleotide: Monomer of DNA
