DNA
DNA = Deoxyribonucleic acid structure is known as a double helix
Contains 4 bases:
Adenine, Thymine, Cytosine & Guanine
Adenine always pairs with Thymine.
Cytosine always pairs with Guanine.
Double Helix is supported by a sugar/phosphate backbone
Segments of DNA are known as genes (genes determine the organism’s characteristics and features in correspondence to it’s parent organisms)
Structure was first described by James Watson & Francis Crick in 1953
Other contributors include Rosalind Franklin & Maurice Wilkins
Double Helix
Similar To Twisted Ladder/Twisted
Staircase
Bases = First Letter Only (A,T,C,G)
A only pairs with T (A ­> T or T­>A)
C only pairs with G (C ­>G or G­>C)
Pentagon = Ribose (sugar)

What Is A Gene?
● Instruction manual for the body (a
Heredity unit)
● Controls particular characteristics
● Genes are the directions for all the proteins in our
