DNA Structure DNA consists of two molecules that are arranged into a ladder-like structure called a Double Helix . A molecule of DNA is made up of millions of tiny subunits called Nucleotides . Each nucleotide consists of: 1. Phosphate group 2. Pentose sugar 3. Nitrogenous base

Nucleotides The phosphate and sugar form the backbone of the DNA molecule, whereas the bases form the “rungs”. There are four types of nitrogenous bases.

Nucleotides Each base will only bond with one other specific base. Adenine (A) Thymine (T) Cytosine (C) Guanine (G) Form a base pair. Form a base pair.

G G A T T A A C T G C A T C DNA Structure To crack the genetic code found in DNA we need to look at the sequence of bases. The bases are arranged in triplets called codons .

This unique sequence of bases will code for the production of a unique protein. It is these proteins and combination of proteins that give us a unique phenotype .
