DNA and
RNA
DNA:
DNA = deoxyribonucleic acid
Contains the genetic code / information
Pentose sugar = deoxyribose sugar
Nucleotide bases
o Adenine
o Thymine
o Cytosine
o Guanine
A=C
G=T
RNA:
RNA = ribonucleic acid
Transfers genetic information and produces amino acids and polypeptide chains
Pentose sugar = ribose sugar
Nucleotide bases
o Adenine
o Uracil
o Guanine
o Cytosine
A=U
G=C
How does DNA structure link to it’s function?
Very long molecule
o Stores a lot of genetic information
Double helix / stranded
o Lots of genetic information can be stored as it’s a compact molecule
o Replication can occur semi-conservatively
Sugar phosphate backbone
