Problem 3. You have performed a mutagenesis screen in Drosophila and have found 5 recessive loss-of-function mutants with an essential role in the neural pathway that allows flies to jump. You perform a complementation test and get the following results. + = wildtype, - = non-jumpers D) How many complementation groups are represented by these 6 mutations? Indicate which mutations are in each complementation group. Problem 4.

Unformatted text preview: Four rII- recessive point mutations were discovered. Coinfections of bacteria with all possible combinations of rII- mutant T4 phages were performed, and the following results were obtained. Fill in the chart 1 2 3 4 1 - 2 - 3 - 4 - A.
