The Transformation of pGLO into Bacteria

what does pglo stand for

This ring can be cleaved and the ampicillin destroyed by the enzyme b - lactamase · b - lactamase enzyme is the product of the bla gene genes are typically lower case and italicized · If a plasmid contains the bla gene, it will confer resistance to ampicillin to the host E. Remove the rack containing the tubes from the ice and place on the bench top. Heat tube to 70 degrees for 10 minutes; store in freezer for next time. Obtain and label 5 different agar plates like shown in table 1 and label them. The bacterium is plated on agar medium containing ampicillin and arabinose. Also, it did not have arabinose to enable the Operon system for glowing. Transfer bacteria into new microcentrifudge tubes and spin them for 1 minute and remove 500 microliters of supernatant, re-suspend bacteria in broth.

We use broth tubes primarily for specific assays, or rarely for bacteria that will not form colonies on a solid surface. This was done a total of four times, one for each tube, using a new inoculation loop each time. Centrifuge tubes for 1 minute and discard the supernatant. Spin in refrigerated centrifuge at 3000 rpm for 5 minutes and discard supernatant. Heat shock the tubes at 42 degrees for exactly 90 seconds and return to ice immediately for 2 minutes. Using a new sterile pipet for each tube, pipet 100 µl of the transformation and control suspensions onto the appropriate plates.

Introduction Plasmids have been studied in genetic research since they were discovered in 1952 by Joshua Lederberg. Add 350 microliters of N3 buffer pH ideal for column binding and mix immediately by inverting the tube. Bacteria use restriction enzymes on their own to get rid of bacteriophages by either cutting the proteins that they make or by cutting the phage directly Aude. Let the flask cool until it you can touch the flask without burning yourself. Unfortunately the mutant samples are not readable. This plasmid has three main coding regions that we will be looking at.

The purpose of this experiment was to explore how genetic information is transferred between organisms by changing the genetic information of E. This is similar to seeing a soapy film across a ring for blowing soap bubbles. By looking at how the bacteria grows and looks we can determine where the transposon inserted; this helps us better understand how genes control traits. The first step was to mix 6. In the gel the addition of the transposon to this region causes the 1,800 bar to stay back to where the 2,800 base-pair bar is and makes it look like just one bar on the gel. Incubate tube at 37 degrees Celsius for 50 minutes, then take tube out and spin again and return tube to incubator for another 50 minutes. Moreover, it did not have arabinose to enable the Operon system for glowing.

The bacteria will both grow and glow. Make sure to push the tubes all the way down in the rack so the bottom of the tubes stick out and make contact with the ice. . Colony that was picked for this experiment was white. The bacteria will glow in which plate? This lab did not only demonstrate and explain why the bacteria would glow under certain conditions, but also combined all the knowledge we have learnt in this unit I mentioned the five main concepts in the background section.

You should take ampicillin when your stomach is empty, which means taking your doses one hour before you eat any food, or waiting until two hours afterwards. We forgot to change our pipettes. There should be a film of plasmid solution across the ring. This biological process occurs in all living organisms, and is the basis for biological inheritance. Then, it produced protein to help it grow. On the other hand, this lab also demonstrates the inducible operon system. Knowing the amount of base pairs that are in the plasmid 5,400 bp and where the restriction enzymes cut we can examine the different pieces of the cut plasmid to find out where the transposon inserted.

Ampicillin is a penicillin antibiotic that fights bacteria. I accept the null hypothesis because the E. For the best transformation results, the change from the ice 0°C to 42°C and then back to the ice must be rapid. The only difference between broth and agar media is that broths do not contain an agar component. There are two types of operon system: 1 repressible and 2 inducible.

Adenine A and thymine T can pair up because they make two hydrogen bonds, and cytosine C and guanine G pair up to make three hydrogen bonds. Use a sterile loop to pick up a single colony of bacteria from your starter plate. Looking at row 7 and 9 there is a missing bar at around 1,800 base-pairs like in rows 3 and 5. The results of this experiment could have been made more significant by being more accurate when measuring the amount of plasmid added to the suspension fluid. This experiment relates to the field of biotechnology because it demonstrates how organisms can be transformed in order to express certain traits. The final result fails to reject my hypothesis.
