- Genes
- Genes carry instuctions that control how you develop and function. They do this by telling the cells to make proteins.
- Genes are sections of long strands of DNA.
- DNA
- DNA is packed into structures called chromosomes (found in the nuclei).
- DNA strands are made of four chemicals called bases. As well as phosphate groups and sugar molecules.
- The order of the bases determine the amino acids produced.
- Clones
- Natural clones = individuals with identical genes. Any differences are due to environmental changes.
- Artificial clones are produced when a nucleus from a body cell is transferred to an unfertilised egg.
