Question
Image that you have a wild type strain and three mutant strains. Each of the mutant strains lacks one gene (the mutant's name is derived from the gene it lacks: gene A, gene B, gene C, or gene D. For example, mutant A lacks gene A). You test all four strains in a bio film assay. The OD values for each strain are: Wild type = 3.4 Mutant A = 3.2 Mutant B = 0.2 Mutant C = 3.3 Which gene is necessary for bio film formation? Select one: Gene A Gene B Gene C There is not enough information to answer this question.Explanation / Answer
Ans. b. Gene B
O.D of wild type strain is 3.4
O.D of mutant B is 0.2 which means a large part of the gene which is GENE B is missing which is responsible for biofilm formation
