- DNA
- Genes
- Human DNA contains approx 25,000 genes
- A single gene codes for a single polypeptide chain
- Found on chromosome
- 'DNA codes for all molecules'
- DNA codes for formation of proteins such as enzymes that synthesis production of other non-protein molecules
- The Genetic Code
- 64 possible combinations for the 4 bases to be read (in triplets)
- Genetic code is widespread but not universal, there are some variations
- DNA location & transcription
- Proteins are formed at the ribosomes
- DNA coding for the formation of protein is too large to leave the nucleus, so the genes required are copied forming mRNA
