Answer #1

Which plate(s) demonstrate transformation has occurred?

Plate A and plate B

The plate containing +pGLO/LB/AMP/ARA, the bacteria glowed, meaning it took in the pGLO gene and with the addition of arabinose, it glows, the bacteria are able to reproduce in a medium with ampicillin. In case of plate B, LB with ampicillin provides a means of selecting transformants that have taken up plasmid DNA containing the bla gene, which is able to encode resistance to ampicillin.

    During a particular transformation protocol, you used a stock of PGLO DNA with a concentration of 0.08 ug ul. You transformed 191 UL of competent E. coli with 100L of PGLO DNA. You added 191 UL of LB broth to the transformation before plating 100 uL of the culture to a plate labeled +POLO, LB, Amp, Ar. After growing the plates overnight, 136 fluorescent colonies (transformants) were counted. What was the average transformation efficiency of your work?

Draw what you ex pect to see on each plate if your assigned plasmid is ampicillin resistant and you looked at them tomorrow. You'll look at them next week - the lab staff will store them at 4C from tomorrow until then so they don't overgrow). Predictions: LB/-P LB AMP/-P LB AMP/+P LB AMP ARA/+P

    Table 5, but this time using PGLO again (NOT PNEW) - your plates are: PGLO-LB/amp, PGLO-LB/amp/ara, PGLO+ LB/amp, PGLO+LB/amp/ara. At the end of the experiment no bacteria grew, so you suspect that a mutation has occurred in PGLO's antibiotic resistance gene. a) What is one alternative hypothesis for why no bacteria are growing on the new plates in any treatment? b) What treatment could you create to test between these two hypotheses for lack of growth?

    .AT&T 12:58 AM 1 0 95% 1:47:09 Exit D5. This week in lab you will observe the results of the transformation that you performed last week. If you were to observe colonies on your - GLO LB/amp plate, what could you conclude? The E. coli carried natural resistance to ampicillin. These are satellite colonies. The transformation results are valid. You forgot to add plasmid DNA to any of your transformations. D 6.

    Cloning 2 Below is the restriction map of a 10 kb piece of DNA. Also shown below is a cloning vector which has two unique restriction enzyme recognition sites, one for EcoRI (E) and one for HindIII (H). The location of the kanamycin (kan) and ampicillin (amp) resistance genes is also shown. Kanamycin and ampicillin are antibiotics that are commonly used to select transformed E. colicells (consult the Lab Manual for more information). Note that the HindIII site is located...
