Nucleic Acids • Function/job: Store important Information in the cell • Made of: nucleotides • Examples: DNA and RNA
Nucleic Acid Structure • A nucleotide is made of 3 components: • Phosphate • sugar • nitrogen base
DNA • Contains information needed for cell activity and cell division • Contains all genetic information • DNA – Deoxyribonucleic Acid
DNA • Structure, It contains • Sugar Phosphate Backbone (deoxyribose) • Nitrogen containing bases (four possible) • Double Stranded
DNA • Double Helix, with base pairing in the center.
DNA • Four Possible Nitrogen Ring bases • ADENINE – A • GUANINE– G • CYTOSINE – C • THYMINE – T Know that: A goes with T G goes with C
The bases are in the inside of the ladder structure they are like the rungs of the ladder. The order of base pairs gives organisms their unique traits DNA Base Pairing
A bonds with T C bonds with G It is estimated that there are over 3 billion base pairs in humans DNA
Complimentary Strand of DNA DNA Strand #1 Double Helix Strand of DNA. –WRITE THE CODE FOR THE COMPLIMENTARY STRAND Dots = Hydrogen bonds
