DNA StructureDNA 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 group2. Pentose sugar3. Nitrogenous base

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

NucleotidesEach 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.

DNA StructureBecause of this complementary base
pairing, the order of the bases in one strand determines the order of the bases in the other strand.

DNA StructureTo crack the genetic code found in
DNA we need to look at the sequence of bases.
The bases are arranged in triplets called codons.

DNA StructureA gene is a section of DNA that codes for a
protein.
Each unique gene has a unique sequence of bases.
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.
