Transcript Deoxyribose nucleic acid

Discovering the structure of DNA
• DNA = Deoxyribose nucleic acid
• Made out of sugars (deoxyribose), phosphates
and nitrogen bases
Discovering the structure of DNA
• Structure was discovered in 1953 by James
Watson and Francis Crick
And I got
to hang
out with
Watson!!!

Cell division and DNA replication
• Cells divide
Growth, Repair, Replacement
• Before cells divide they have to double cell
structures, organelles and their genetic
information
DNA replication
