to successfully infiltrate E. coli bacterial cells with a pARA-R plasmid that is antibiotic resistant and has the rfp gene‚ or red fluorescent protein. This can be verified if the E. coli obtains the characteristics of the plasmid when it enters. To start‚ three Petri plates containing agar are needed. On each plate there is a control group and a treatment group; the treatment group being the one with the plasmid. Before the plasmid is put with the E. coli‚ first the bacteria are “stressed out” by

electrophoresis. Lane 7: 10 µL of ladder. We began our goal of combining DNA by obtaining the desired samples of plasmid DNA from a liquid bacteria culture. Plasmids are circular pieces of DNA‚ which can be found in bacteria. Plasmids are often used in the manipulation of genes. After carefully following a mini-prep procedure‚ we were left with samples of pAMP and pKAN plasmids. pAMP is a bacterial plasmid‚ which contains the gene ampR. The ampR gene codes for a protein that breaks down the

Resultant Recombinant plasmids in this experiment had multiple inserts leading to inconclusive orientation of the inserts; however this can be tackled by Sanger or Maxam/Gilberts sequencing.

toward Ampicillin due to Plasmid and DNA Consumption U34 Abstract During the ampicillin experiment the ability to transform cells to make them adaptable to their environment was studied. The E.coli bacterial cell was used in order to observe how its DNA was able to change and develop immunity towards ampicillin. In order for this change to occur the use of several plasmids was needed. The plasmids used in this experiment were pUC18 and the lux plasmid. The E.coli cells that

DNA cloning: the basics Page: 307 Difficulty: 1 Ans: C Restriction enzymes: A) act at the membrane to restrict the passage of certain molecules into the cell. B) are highly specialized ribonucleases that degrade mRNA soon after its synthesis. C) are sequence-specific DNA endonucleases. D) are very specific proteases that cleave peptides at only certain sequences. E) catalyze the

purpose of this experiment is to determine the effects of the addition of a plasmid to a bacterial cell. The bacteria E. Coli was separated into two groups: one where the pGLO plasmid was added to the bacteria‚ which contains the genes of fluorescence and resistance to antibiotics‚ and the other lacking the plasmid. The two groups then placed in agar plates simulating different environments: the bacteria lacking the pGLO plasmid was subjected to an environment solely contaiing nutrients and another containing

Using DNA in Science and Technology DNA is the blueprint for life‚ it is found in the nucleus of cells on the chromosomes. It is found in many cell organelles‚ such as plasmids in bacteria‚ chloroplasts in plants‚ and mitochondria in both plants and animals. DNA helps us to perform many actions in solving crimes‚ and also helps us to do scientific studies that were not possible until recently. DNA has a double helix structure‚ its sugar phosphate backbone‚ made up of deoxyribose and a phosphate
