Bacterial transformation is theeasiest type of genetic transformation to create in a lab due to the singlecelled nature of bacteria. To determine the cause of thisanomaly the variable lab could be repeated to see if the results were similar. In the lbamp plate treated with the -pglo sample absolutely no bacterial growth was observed.
In the lbamp plate treated with the -pglo samplea few small yellow colonies appeared, spread randomly across the plate. For example,plants can be given plasmids so that they gain certain traits, such asresistance to disease or extreme weather. The transfer pipettes used during muchof the procedure werent very accurate, since any variation of the pressureapplied to the pipette would change the volume.
The other two, (lbamp) and (lb) were covered in a solution consisting ofonly the transformation solution and lb broth. Many ethical dilemmas like these become evident when workingwith and altering living organisms for the sake of scientific inquiry howeverthere are many positive benefits to genetically engineering bacteria. In the control lab a differentoutcomes was observed in each of the four plates.
Without the beta sample a small amount bacterial growth was seen. Once rnapolymerase has attached to the promoter, transcription of the gfp gene beginsand continues until isoften used to fight bacteria in the human body, specifically various types ofinfections. This might have been because of cross contamination orincorrectly timing the temperature shocks used.
In thelbampara of the appendix section shows the calculations for the transformation efficiency on the lbamp plate where no transformation solution was used. . In the lbampara sample many yellow, differently sized colonies grew, whichfluoresced green under ultraviolet light.
Even if only one colony is taken, it is unlikely thatany two colonies are exactly the same size. This inaccuracy could beeliminated by using micropipettes, which are accurate to the in the variable lab, the lack ofcalcium chloride solution had different effects on both pglo plate no plasmid was incorporated into the cells, but on thelbamp plate the plasmid was at least partially taken up by the cells. Researchers at tel avivuniversity have even been able to manipulate bacteria so they light up whenthey come in contact with certain pollutants in water. There were 67 transformants per micro gram on the lbamp plate. G8( ee fro its prooter to be fter coclu!i this e.
There are many ethicaldilemmas associated with this lab because of the nature of this experiment. We anticipated that the lbampara plasmid dna would become fluorescent. The results in the second test showedthat the calcium chloride solution is essential to efficient plasmid uptake,but to what degree was not determined. Forexample, scientist have been able to genetically engineer forms of e. Bacterialtransformation occurs if a bacterium uptakes a piece of dna and integrates itinto its genome.
The other four plates werethe exact same, except none of them were covered with a solution that containedthe calcium chloride instead distilled water was combined with the lb brothand plasmiddna. Such infections may include causedby bacteria, like ear infections, bladder infections, pneumonia, gonorrhea, and during the course ofthis experiment, our objective was to manipulate a variable present within thelab and determine what affect this change would have on the results of the lab. In the lbampplate containing the pglo sampleseveral large, yellow colonies appeared, some grouped in clusters and othersspread over the plate. In the lb plate containing the -pglo sample, bacteria grew evenly on the plate in the areas where itwas spread with the transfer loop. Researchers at tel avivuniversity have even been able to manipulate bacteria so they light up whenthey come in contact with certain pollutants in water.
Green fluorescentprotein, or gfp, is found naturally in the luminescent jellyfish victoria. Many ethical dilemmas like these become evident when workingwith and altering living organisms for the sake of scientific inquiry howeverthere are many positive benefits to genetically engineering bacteria. Do single celled organisms have fewer rightsthan us? Why should we be able to grow and kill these organisms at our owndiscretion? Who decides whether or not it is just to alter or work with certainorganisms? The opinions on such a subject are very diverse, leaving us with nodefinitive answer. Once rnapolymerase has attached to the promoter, transcription of the gfp gene beginsand continues until isoften used to fight bacteria in the human body, specifically various types ofinfections. Due to the multiple solutions andbacterial plates used in this lab there it is likely that some crosscontamination occurred. . The thir!
