DNA is Genetic Material

DNA stands for DEOXYRIBONUCLEIC ACID:

• Controls protein production in cells.
• Made up of many genes which controls traits

Why DNA is Important?

• Passes genetic information from generation to generation.
• Traits are controlled by DNA.
• DNA replicates with little error.
• Can not live without DNA because it part of everything in the body.

DNA Structure

• DNA is a double Helix meaning DNA has two strands. It looks like a twisted ladder.
• DNA is polymer made up of units called NUCLEOTIDES

The nucleotides joined together in a long chain
