DNA - double helix shape
A section of DNA is called a gene
Gene carries information which forms the characteristic of organism
e.g. blood group, petal colour, etc. (different genes for different characteristics)
- Genes are located in the nucleus
- Information is passed to the cytoplasm
- Information is transformed into protein (inside cytoplasm)
Information flow:
Gene (nucleus) -> Protein (cytoplasm)
