BIO 1A03 Test 2 Questions and Answers Already Passed one gene-one enzyme hypothesis each gene contains the information needed to make an enzyme What did George Beadle and Edward Tatum research? Relationship between genes and proteins using the Neurospora Crassa One gene-one enzyme hypothosis (Neuroposa Example) Neurospora can grow well on minimal medium (simple sugar, vitamins, inorganic salts), and therefore it must have enzymes produced by a certain gene that that transform these materials i...

IGCSE Biology Exam - Paper 6 Revision Notes BIO Enzyme activity lab: 2H2O2 (l) → 2H2O (l) + O2 (g) This reaction can be catalysed by an enzyme (catalase) or by a non- biological catalyst (Manganese IV oxide) 1. Put 3cm2 of hydrogen peroxide in a test tube. 2. Add fresh potato strips and shake gently. 3. Keep your thumb on top of the test tube, or use a stopper, to retain the gas. 4. Do the “glowing splint” test → the splint relights Positive control: repeat the original experime...
