Across
- 2. variable - affect by other variables
- 4. - more than one code for the same amino acid
- 6. reactions - exothermic reactions which break down large molecules and supply energy
- 7. Cloning - isolating and making a copy of the gene
- 9. - different versions of the gene (one from each parent)
- 11. - number of same species in a specific area
- 13. - all the same type of atom
