Questions 35 and 36 refer to the following. Sh own below are the complementation test results involving 4 in dependently Complementation was with two assayed by simultaneously infecting bacteria phage strains, each with a different mutation, neither of which could alone lyse the cel the table below, a "+ dcates the strains complemented each other and therefore lysed open the bacteria. A "0" indicates therefore no cell lvstis A o" indicates no complementation and therefore no cell lysis occurred. 0 The SAME data can also be expressed in the following format. Use the format you understand best to answer the questions. Test pair Results 1,2 1, 3 1,5 2, 3 2, 5 3, 5 4, 5 35. How many genes are there? a) one b) 2 c) 3 d) 4 36. Which of the following strains have mutations are in the same gene? a) 1 & 2 b) 1 &5 c) 1&3 d) 2&5 e) 3&5Explanation / Answer
There are two strains of becteria with different mutuation and these two phage strains work together (where one is +ve strain which is infected and other one is '0' strain which is not infected)
35.( c) Three genes are present (1,2) (1,3) (1,5) these three stages are infected because they are complementary to each other.
36. (e) (3,5) strains have motation in the same gene and there is (1,4) also have mutuation in the same gene but 1,4 strain is not has given in the following options.
