Rosalind Franklin
Watson & Crick
What is DNA ?
• DNA = Deoxyribose nucleic acid
The sides are made of ___________________
The rungs are made of ___________________
• Shape = _______________________________
Double Helix polymer
Nucleotides

• One nucleotide
Is made of …
______________
______________
______________
• Draw one NucleotideH
Deoxyribose
A,T,G and C - The letters of life
A = __________________ T = _________________
C = __________________ G = _________________
If you were to start reciting the order of the ATCGs in your DNA tomorrow morning, at a rate of 100 each minute, 57 years would pass before you reached the end…
Base Pairing
A = T & C = G
Drawing DNADrawing DNA
Complete the DNA
strand by drawing in the correct matching
nitrogen base, then
complete the side of phosphorus
and sugar.
Triplet
The code within DNA is based on a triplet system…
DNA codes in three letter words……
What is a gene?
A human chromosome has thousands of genesEach gene is a recipe for a protein!
Chromosomes
Genome
Collection of genetic
information within all
genes contained in
the DNA molecule(s)
in a cell.
If the genome was a book, it would be the equivalent of 800 dictionaries. It would take a person typing 60 words per minute, eight hours a day, around 50 years to type the human genome.
