Document Summary
Question 1 what is the purpose of: genes, cell division, mitosis, meiosis, eukaryotes alternating between haploid and diploid, recombination during meiosis, meiotic crossovers. Question 2 consider the experiment done by srb and horowitz (lecture 5 section 3): the symbol "+" is used to represent three different things. What are they: positive and negative controls are done so that we know that an experiment has worked the way it should. Use a wt strain of neurospora instead of the arg3- strain. Question 3 students often confuse biochemical pathway analysis with complementation tests. To illustrate the differences consider this synthesis pathway from s. cerevisiae. You have isolated three mutant strains unable to synthesize compound b . The blocked step in each mutant strain is shown. Mutations 1 and 3 are in the same gene. Complete both tables with the expected results where + indicates growth and - indicates no growth.
