1 DNA The illustration is a ‘model’ of the double helix forming part of a DNA molecule (Slide 14)

DNA DNA stands for deoxyribose nucleic acid 2 DNA stands for deoxyribose nucleic acid This chemical substance is present in the nucleus of all cells in all living organisms DNA controls all the chemical changes which take place in cell. ***The kind of organism which is produced (butter-cup,giraffe, herring, human etc.) is controlled by DNA

DNA molecule DNA is a very large molecule made up of a 3 DNA is a very large molecule made up of a long chain of sub-units The sub-units are called nucleotides Each nucleotide is made up of : a sugar called deoxyribose 2. a phosphate group -PO4 and 3. an organic nitrogen base

Both molecules may be represented by the 4 Deoxyribose is almost the same but lacks one oxygen atom Both molecules may be represented by the symbol

The bases The most common organic bases are Adenine (A) Thymine (T) 5 The most common organic bases are Adenine (Purines) (A) Thymine (Pyrimidines) (T) Cytosine (Pyrimidines) (C) Guanine (Purines) (G)

Nucleotides The deoxyribose, the phosphate and one of the bases 6 The deoxyribose, the phosphate and one of the bases Combine to form a nucleotide adenine deoxyribose PO4 It is the phosphate group which gives DNA its acidic properties

Joined nucleotides 7 PO4 sugar-phosphate backbone + bases A molecule of DNA is formed by millions of nucleotides joined together in a long chain

In fact, the DNA usually consists of a double strand of nucleotides 8 In fact, the DNA usually consists of a double strand of nucleotides The sugar-phosphate chains are on the outside and the strands are held together by chemical bonds between the bases

2-stranded DNA 9 Sugar Phosphate bonds Chemical Bonds PO4 PO4 PO4 PO4

14 THE DOUBLE HELIX bases sugar-phosphate chain

Bonding 1 The bases ALWAYS pair up in the same way 10 The bases ALWAYS pair up in the same way Adenine (A) forms a bond with Thymine (T) Adenine Thymine and Cytosine (C ) bonds with Guanine (G) Cytosine Guanine

11 Bonding 2 PO4 adenine cytosine PO4 thymine PO4 guanine PO4 PO4

13 The paired strands are coiled into a spiral called A DOUBLE HELIX
