Homework Answers
I believe the correct answer to be:
Option B) A plate with 100 colonies growing on LB agar with kanamycin.
As the cell will be able to grow in presence of kanamycin but since the transformation effeciency is generally not very high, there is very low probability that a lawn will be grown.
feel free to leave a comment down below for any further query. good rating would be appreciated if you find my answer helpful. thank you.

You set up a transformation hoping that a strain of E. coli will take up a plasmid containing an ampicillin resistance gene, making the strain able to grow on LB + amp. To see if the transformation worked, you set up four plates: (1) Untransformed E. coli cells on LB plate (2) Untransformed E. coli cells on LB + amp plate (3) Transformed E. coli cells on LB plate (4) Transformed E. coli cells on LB + amp plate. Your...

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...

You add (1.04x10^0) ng of plasmid DNA in 50 µL to 100 µL of competent E. coli cells and incubate the mixture on ice for 20 min. Following a heat-shock treatment, the cells are incubated at 37 C for 30 min. At the end of the incubation you spread (1.2000x10^2) µL of the transformation mix on an agar plate and incubate the plate overnight at 37 C. The next morning you observe (6.8400x10^2) colonies on the plate, each colony having...

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?

This is what we did in the experiment .First of all,1 µl of
plasmid DNA was added into the tube which contains competent cells
and the tube was tapped gently to mix DNA and the competent
bacteria. After that it was placed on ice for 30 minutes. Then, the
tube with the competent bacteria and plasmid were transferred to
heating block at 42 °C and the tube was leaved in there exactly 90
seconds. 0.25 ml of LB broth was...

You have a stock of an E. coli cell culture of an unknown concentration. You want to set up a serial dilution experiment so that you can count the viable colonies and determine the concentration of the stock in cells/ml. In tube A, you add 1 ml of the stock to 999 ml of media. In tube B, you add 1 ml of the material from tube A to 24 ml of media. In tube C, you add 50 microliters...
