DNA, RNA & Heredity Genetic Code
Information is Stored in the Code Letters of DNA
- All hereditary information is stored in genes, which are parts of giant DNA molecules
- Genes code for the amino acids of proteins
- DNA is the archival copy of the code- kept in nucleus where it is protected & repaired
- DNA is organized with special proteins into chromosomes
- For protein synthesis a working copy of the code is made from RNA
- Overall scheme: DNA -> RNA -> protein
- Another version: “One gene, one enzyme”
