4. You've run an interrupted mating conjugation experiment with Hfr cells that are hmm* omgpoot and streptomycin resistant (str). Your recipient cell is F-hmm omg poo' and streptomycin susceptible (str). Below are the results from that interrupted mating experiment. frequency of Hfr genetic characters among str-resistant exconjugants a) If you attempted to grow your exconjugants (those recipient cells that underwent conjugation) at 20 minutes on a complete media plate that contained streptomycin, would you expect to see growth? + X...

This is a Hfr mapping question and I'm completely lost
here
Basically the bonus is a puzzle. It is based on mapping done with 4 different Hfr strains. I've given you the minutes that that it takes for several of the markers on the map to transfer in as determined by Hfr mapping. All you have to do is put them in the correct order around the circular chromosome and show me how many minutes are in between each marker...

2. You have performed the following mating experiment using Hfr and F"strains of Escherichia coli:(4 marks) Hfr (asp+ trp+ mal+ StrepS) x F (asp-trp-mal- Strep). Strep = streptomycin, an antibiotic Asp = aspartic acid, an amino acid Trp = tryptophan, an amino acid Mal = maltose, a sugar molecule, can be used by some organisms as an energy source rather than glucose (a) What selective media would you use to score recombinant colonies that have received all of the markers...

In this problem you will explore how to solve problems involving partial diploid lac operon bacterial strains. Bacterial strains that are "partially diploid" have two copies of the lac operon because they aquired a plasmid carrying just the lac operon region. One copy of the lac operon region is on the recipient's bacterial chromosome, and the other copy is on the F' plasmid that was introduced into the cell by conjugation. Partial diploid genotypes are written with the F' segment...
