In this experiment there were main 4 hypothesis made according to each agar plate each with a different types of genes on them. There are two genes that are on the agar plate and not in the solution it is the ampicillin and the arabinose genes. The ampicillin gene (amp) is a gene which acts like an antibiotic that kill the bacteria but when used with the pGLO plasmid it lets it survive because of the ampicillin resistant. The arabinose
Out of all the acids that passed through, only one was found to be toxic. By using high performance liquid chromatography, a polar and nonpolar stationary phase that contained the toxin was mixed, and this isolated the toxin by itself. To ensure that that was the isolated toxin, they further broke it down to find its charge, size, and molecular shape. Mass spectrometry was then used to find the weight and formula of the toxin. By finding the formula, it had similar characteristics to an amino acid known as domoic acid.
They are both very soluble in alcohol and hexane so that doesn’t help, but in water ethyl ether is semi soluble and pentane is in soluble. This would make us lean toward pentane but we felt strongly that ethyl ether because of the density was a much better test because there is much less human error and the we asked about how do you decide if something is insoluble
It is stated on www.biologyinfo.com that, “Not all bacteria are harmful. In fact, less than 1 percent cause disease, and some bacteria that live in your body are actually good for you”. However there are some bad bacteria which cause diseases such as, MRSA, strep throat, tuberculosis, anthrax and urinary tract infections. Viruses are a great deal smaller than bacteria. They are contained in a protein coating which makes them more difficult to destroy.
The substance dissolves in water but not in alcohol, is transparent when dissolved in water, is electrically conductive when dissolved in water, dries white, and has a high melting point. Out of the four compounds we received to test, according to the data we collected, sodium carbonate was the one that would work the best as a fixative for the glaze. In the experiment we conducted you will notice that the independent variables were the different compounds, while the dependent variables were the results to the criteria that had to be met. Also, during our research, we found that sodium chloride and sodium carbonate worked better than sucrose and salicylic acid because they have ionic bonds. These conditions are more suitable for ionic bonds.
Protects the bacteria from phagocytosis allowing the bacteria to stay in the body 6. pure culture 7. It is differential based on hemolysis of the agar. Hemolysis can be wide-narrow band beta, alpha, gamma, or none. 8. candle jar in microbiology is used for anaerobiosis in which a lit candle is placed in an air tight jar and if it went out, it would be because it used up all the available oxygen. 9. any streptococcus capable of hemolyzing erythrocytes, classified as α-hemolytic type, producing a zone of greenish discoloration much smaller than the clear zone produced by
There is free rotation around this group because resonance is limited to resist the free rotation. 5) What is a Ramachandran plot and how does it relate to bond rotation in peptides? Ramachandran plot is a visualization method of dihedral angles φ against ψ of amino acid residues in protein structure. Overall, it provides the different confirmation possibilities of the two. 6) Which amino acid has more restrictive bond rotation and why?
Two for E.Coli and two for S.Albus. One of the two was tested for the affect on bacteria with 1) Mouth wash, 2) Bleach and 3) Dettol. The second one of the two was tested with the antibiotic mast ring. The results obtained; + means positive (Worked) - means negative (Didn’t
The overuse of antibiotics enables the bacteria to build up immunity to antibiotics so that they are less effective. MRSA bacteria normally lives on the skin and in the nose without causing problems. According to the Centers for Disease Control and Prevention, less than 2 percent of the population carries the type of staph bacteria known as MRSA (Mayo Clinic Staff). It is when a infection occurs that the bacteria becomes a problem.
Another group of drugs were developed which specifically targeted serotonin and these are known as SSRIs (selective serotonin reuptake inhibitors). These work by blocking the reuptake of serotonin and they have a negligible effect on noradrenaline. SSRIs became extremely popular with GPs due them being so effective (twice as effective as placebos) and having less side effects than previous antidepressants. It has been
