Practice Problem 30 In an experiment similar to the Lederterg and Tutunexperiment, E col strain Ax has the genotype Amp bio+ trp+ E col strain AY has the genotype Amprbio trp-leu+. The researchers then plated the bacteria on dterert meda types. oomplete medum complete medium ampicilin Submit My Answers Give Up Correct Bactria that are Amp are resistant to ampicilin and can grow in the presence of ampielen a strain of bacteria is wildtype for make an essential nutrient (for example Anut then the strainoan grow in meda that lacks that ntrent. Part C Next, the researchers mixed equal amounts of theAX and AYE coi strains. which type(s) of meda would growth provide evidence that genetic transfer had oooumed between the two strans of Select all that apply bio-leu. bio-trp- leu- trp- bio- none of the above Submit My Answers

Solution

The Options a,c,d are correct.

Since, if a recombination happens where leu+ gets transferred then one strain(bio+ trp+ leu+) will be formed that will grow in a medium where bio,leu and trp need not be given

Again if either trp or bio gets transferred then 2 kinds strains (bio- trp+ leu+ and bio+ trp- leu+) will be created which can grow in media where trp,leu and bio,leu need not be given respectively
