Hi science folks! I am trying to explain the distribution of mutations base in mutagenesis experiments. I calculate mutation frequency based in number of mutants obtained from the total growing, but in order to set the distributions, I have seen the use of an old formula for the mutation rate: -(ln(m0)/n), being "m0" the number of experiments with no mutants found (fraction of 0) and "n" the average bact/ml. However, the mutation rate should be a mesure of mutation per time, so it doesnot seem to me totally appropriate or perhaps I do not understand the maths behind. Is there anyone who used this or other parameters and can help me to understand it? Thanks a lot!
