2.6 Structure of DNA & RNA
DNA
Deoxyribonucleic acid
Four nitrogenous bases
Guanine (G)
Adenine (A)
Thymine (T)
Cytosine (C)
The structure of DNA allows efficient storage of genetic information
Polymer of nucleotides which form a strand
The strand consists of a backbone of sugar molecules and phosphate groups
Bases are attached to the sugars
Nucleotides
Composed of three parts
Pentose sugar (five carbon atoms)
Phosphate group
Nitrogenous base
Double stranded molecule
Is the genetic material of living organisms
RNA
Ribonucleic acid
Four nitrogenous bases
Adenine (A)
Uracil (U)
Cytosine (C)
Guanine (G)
