Using mutants 2 and 3 from Problem 19, following mixed infection on E. coli B, progeny viruses were plated in a series of dilutions on both E. coli B and K12 with the following results. What is the recombination frequency between the two mutants? Strain Plated Dilution Plaques E. coli B 10⁻⁵ 2 E. coli K12 10⁻¹ 5

Hello everyone. And here we have a question asking what is the main purpose of the serial dilution technique? So the serial dilution technique is used when the number of colonies is too big to count. And in this process, a series of sequential dilution czar performed to convert a dense solution into a more usable concentration. So our answer is c to reduce the colony number to the point where it can be accurately counted. Thank you for watching. Bye.
