One Gene One Polypeptide Mendel found certain  “factors” were responsible for  the patterns of inheritance  seen in pea plants We now know these “factors”  are genes  Genes determine what  proteins are synthesized Proteins are responsible for cellular processes, help  determine physical characteristics and genetic  disorders.

Garrod’s Hypothesis One gene = one polypeptide Hypothesis: patients with alkaptonuria have a  defective enzyme that is due to a genetic  defect. After analysis of blood, urine, and family history Due to lack of enzyme that metabolises alkapton Excreted by urine and turns black when oxidized Enzyme production directed by genetic  material.
