Essay on Bacterial Transformation Report

Bacterial transformation occurs when an organism receives DNA from a different species and expresses the implemented gene, thus becoming a transgenic organism. The practice proceeds as follows: first cut the plasmid from one organism and DNA from another, using the same restriction enzyme on a palindromic sequence. The recombinant plasmids then enter the host bacteria and asexually reproduce infinitely. We can identify that the bacteria has the new DNA by testing to see if it expresses the trait. We can…

Pglo Lab Report

Purpose The overall purpose of the pGLO lab was to transform E. Coli bacteria by adding materials such as luria broth, ampicillin, plasmid, and transformation solution. Transformation is a process in which one strain of bacteria is changed by a gene or multiple genes from another strain of bacteria. Procedures The first thing done for this lab was prepping the plates. Students labelled the plates, and then teachers put in agar agar in each plate, adding either pGLO plasmid, ampicillin, or arabinose…

and 234 237 in your textbooks. DNA sequencing DNA technology and genetic engineering Recombinant DNA: A plasmid is extracted from a bacterial cell and then using restriction enzymes, is cut open. Also a gene is extracted from a human cell. using the same restriction enzyme as before to ensure that the gene can be placed in the plasmid. The gene is placed in a solution with the plasmid and then they combine. The plasmid is placed in a bacteria cell and the bacteria cell multiplies. The bacteria without the desired gene are thrown away…

Pglo Transformation Lab Report Essay

microbiologist. Griffith observed that the mutant form, non-virulent form, of the bacteria Streptococcus Pnumoniae could be transformed into the normal, virulent form, when injected into mice along with heat killed normal forms. He concluded that somehow the information the dead virulent form had transformed the mutant form into a virulent form. Later on through the works of Avery, Macleod, and McCarty in 1944, it became obvious that DNA is the transforming property and the substance…

Agarose Gel Electrophoresis

The purpose of this experiment was to replicate DNA by using Polymerase chain reaction by observing and analyzing it by agarose gel electrophoresis Genetic transformation is defined as the process where by a plasmid is introduced into a cell such that when the cell reproduces, it also makes a new copy of the plasmid. Plasmid is defined as a circular DNA particle that is within a microorganism and has a replicating quality that are autonomous. Escherichia coli, is a bacterium that is commonly used…

Essay about Background Reading Reading Notes

CHAPTER 5: LIGATION Background Cloning Vectors Pgs 94 - 101 Once a gene or part of a gene has been amplified using PCR, the next step in cloning is to insert the DNA into a plasmid or cloning vector so that the fragment can be propagated. Gene is amplified  insert DNA into a cloning vector to be grown. a vector is defined as an organism that transmits an infectious agent from one host to another (Infectious disease definition) A vector is an agent (such as a bacteriophage or plasmid) that is…

However, give rational for your methods here, i.e. “The cell membrane was disrupted by treatment with NaOH/SDS”; “Plasmid DNA was precipitated using potassium phosphate”. Results A section containing the raw data and statements of what “is”, not what the data “might” mean. Tables, graphs are usually presented here to summarize the results Same. Discussion A section…

16s Rrna Synthesis Lab Report

Bacteria are present on everything and everyone. There is such an abundance of bacteria, that all the different species have yet to be discovered (source). Despite there being billions of bacteria, they all share one common trait which is the 16S rRNA gene. The 16S rRNA gene is a universal gene in all bacteria and that is why it was chosen for this experiment. Using the 16S rRNA makes it possible to identify the species based on its gene sequence. (Clarridge, J. E.2004) The purpose of this experiment…

detect if the bacteria contains any deoxyribonuclease activity. Because no color change was observed from blue to clear my unknown bacteria displayed a negative result. Blood agar plate This test is used to detect the hemolytic activity in the bacteria. A darkish green color on the media around the bacteria would represent incomplete hemolysis. A transparent media around the bacteria colony represents complete lysis of the red blood cells. If no change is observed around the bacteria colony then…
