Homework Answers
a. The alternative hypothesis for why bacteria didn't grow might be that in the antibiotic resistance gene there may be a gene inserted which inactivated the antibiotic resistance gene.
b. To experiment this hypothesis, we can seqeuence the antibiotic resistance gene and check where the mutation has occurred or another gene was inserted.
If you have any query kindly comment before giving thumbs up. Thank you.

.1)a) Why was it important that the –pGLO bacteria were found growing on the LB plate? Why would their absence create problems in interpreting our results? b) What two conclusions (one per plate) should you draw from the observation that –pGLO bacteria did not grow on the LB/amp plate, but that some +pGLO bacteria did? c). Why did we observe bacteria colonies that glowed under UV light when we inoculated +pGLO bacteria on an LB/amp/ara plate, but not when we...

Suppose that you carried out a Bacterial transformation of E. coli HA101 with pGLO plasmid experiment in the lab. During the experiment plates with bacteria were inoculated from +GLO and -GLO microfuge tubes (LB (-) plate, LB/amp (-) plate, LB/amp (+) plate, and LB/amp/ara (+) plate). 14) Explain what kinds of bacterial growth you will find on each of 4 plates after incubation ((LB (-) plate, LB/amp (-) plate, LB/amp (+) plate, and LB/amp/ara (+) plate): under normal light and...

2. Bacterial transformation occurred on which agar plate (s)?
What evidence do you have that the bacteria were transformed
here?
3. Which plates have glowing growth? Explain what causes
bacteria to glow.
