- They are really long molecules of DNA
- DNA contains all instructions that enable it to construct and organism and make it work
- It is found in the nucleus of both animal and plants cells in VERY long molecules called chromosomes.
- DNA stands for DeoxyriboNucleic Acid
- A gene
- It codes for a specific protein. A gene is also a section of DNA.
- Genes tell cells what order to put the amino acids in.
- DNA determines what protiens the cell makes
- Haemoglobin and Keratin
- AND DNA determines what type of cell it will be e.g. red blood cell or skin cell
- Cells can make protiens by stringing amino acids together in a particular order.
- Only 20 amino acids are used. But they make thousands of different proteins.
- It codes for a specific protein. A gene is also a section of DNA.
