You perform transduction experiments to determine the genetic map of four genes: bio, met, lac, and pro. You find that met and pro are cotransduced at a frequency of 80%, met and lac at a frequency of 50%, lac and pro at a frequency of 40%, pro and bio at a frequency of 30%, and lac and bio at a frequency of 10%. What is the order of the four genes?
A)lac bio met pro
B)pro lac met bio
C)met lac bio pro
D)lac met pro bio
E)bio met lac pro
please explain me.
Homework Answers
Option (c) is correct .
Order of the genes is given below:–
Met <lac < bio < pro.
From co- transduction frequencies given in the question,we can conclude the gene order.
In gene mapping, there is inverse relationship between co- transduction frequency and gene distance.
# the greater the cotransduction frequency, the closer two genetic markers or genes are and the shorter is the map distance and vice-versa.

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 identified a mutant E. coli strain that cannot synthesize histidine (His). To determine the location of the his mutation on the E. coli chromosome, you perform interrupted mating experiments with 5 different Hfr strains. The following chart shows the time of entry (minutes, in parentheses) of the wild-type alleles of the first 5 markers (mutant genes) into the His strain. + + Hfr A. Hfr B Hfr CH Hfr D.

Please explain step by step... thank you!
In order to determine the overall chromosome map for E coli, three Hfr strains were obtained from a protrophic but erythromycin resistant F+ ancestor. The start times of transfer during conjugation matings with F- strains carrying auxotrophic, fermentation, and erythromycin- sensitivity markers were determined for each Hfr strain, as listed. A. Using the times for transfer of each marker, draw a unified chromosome map of E coli, showing the order and relative distances...

Study the below figures that show experiments on transgenic mice. In experiment one, the mice have either a single transgenic copy of A, a single transgenic copy of B, or copies of both A and B. In experiment two, the mice are homozygous for no deletion of gene C(C+/C+), heterozygous for gene deletion (C+/C-), or have double deletion of gene C (C-/C-). a) Of genes A, B, and C, which ones are oncogenes and which ones are tumor suppressor genes?...
