The vital components and techniques of gene cloning are as follows, the DNA sequence that contains the desired gene (EZH2) is amplified by Polymerase chain reaction. PCR was established by Kary Mullis in 1985, popularly known to amplify target sequences of DNA (EZH2) to a billion fold in several hours using thermophilic polymerases (Taq) ,primers and other cofactors (Sambrook and Russell, 2001). Three crucial steps are involved which are Denaturation (at 95°), Annealing of the forward and reverse primers (55-65°) and lastly primer extension (at 72°). After amplification the desired sequence is integrated into the circular vector (pbluescript) forming the recombinant molecule. For the compatibility of the insert and vector, both were digested with (EcoR1) so the same cohesive ends are generated in both, making it easier to ligate. EcoR1 is a restriction enzyme that belongs to the type II endonuclease class which cuts within dsDNA at its recognition site “GAATTC” (Clark 2010; Sambrook and Russell, 2001).

The last half of the book continued to follow Cece working on making friends and dealing with how she feels about her hearing. She also moves and makes a new friend, Martha. She also makes friends with her neighborhood children. Martha is a grade below her and they get along great. Cece assumes that Martha doesn’t know that she is deaf, because it is summer and they aren’t in the same class together in school and hasn’t seen her wearing the Phonic Ear. However, she does know and simply doesn’t care. The neighborhood kids are also kind to her and there is a neighbor boy Mike Miller that she has a crush on. All is well until Martha hurts Cece’s eye and panics. Her eye heals but Martha is still too afraid to be around

Thiol groups are important to protein folding and forming disulphide bonds that are essential to protein structure. Determining the number of thiol groups in a protein is important in determining the tertiary structure of the protein. The ovalbumin is the experiment was purified from egg white using centrifugation and ammonium sulphate precipitation and then the thiol groups identified using DTNB and spectroscopy. The ovalbumin was found to have one thiol group; from this we were also to infer that DNTB alkylates thiolgroups; whereas SDS keeps proteins denatured.

Second, in order to further confirm the information about characteristics and function of the targeting protein that we have

For PEI Transfection, we added 1 ml of Trypsin to a T-25 flask of 293T cells and incubate at 37 0C for 10 minutes. Then, we supplemented 10 ml of DMEM (2.5%), FBS (15), P.S medium to the flack and finally transferred to dish and put back in CO2 incubator. After 5 days, we diluted plasmid DNA (ug) in 250 ul of 150mm NaCl in a sterile tube, and diluted 40 ul of PEI into 250 ul of 150 mm NaCl in second sterile tube. After that, incubated each separate tube for 5 minutes at RT and then mixed the DNA tube with the PEI tube. We put the tube in incubator for 2-5 minutes at RT, supplemented dropwise to cells, and put back into incubator. The important steps that was added helper virus (VSV) to cells and put it in the CO2 incubator; then, collected supernatants that contains our

“The Mouse” is a short story written by H.H Munro. The main characters are Theodoric, the mouse, and the blind lady. The author Munro writes the story in third person and uses an omniscient view. The setting of the story takes part in the vicarage, the stable, and the ends in train compartment. The tone used by the author to engage his readers is an exciting, thrilling fast paced tone that bring the characters to life. To strengthen the thrilling exciting tone, the author uses phrases such as: “he was not even alone in his own clothes. “A warm, creeping movement over his flesh betrayed the unwelcome and highly resented presence, unseen but poignant, of a strayed mouse.” After reading the quote above, I as the reader was drawn into the

Proteins are polymeric chains that are built from monomers called amino acids. All structural and functional properties of proteins derive from the chemical properties of the polypeptide chain. There are four levels of protein structural organization: primary, secondary, tertiary, and quaternary. Primary structure is defined as the linear sequence of amino acids in a polypeptide chain. The secondary structure refers to certain regular geometric figures of the chain. Tertiary structure results from long-range contacts within the chain. The quaternary structure is the organization of protein subunits, or two or more independent polypeptide chains.

After finishing the experiment in its entirety I discovered that the hypothesis was supported. The information that came from the sequenced DNA of a Drosophila specimen clearly coded for a protein that was akin to that of humans. It was not 100% related, however it was 87% similar which is a very close match. There would have definitely been a closer match, but human error can account for some of the issues that may have caused it to not be a 100% match. Since the proteins are a very close match we can conclude that certain Drosophila proteins can be homologous to human proteins that are involved in human diseases and other illnesses.

The starting amount of synthetic mRNA was 100 nmol but was split into two Eppendorf tubes of 50 nmol each, with 5 nmol of spin label for each tube. Since the R5 spin labels are hydroscopic and light sensitive, they were purged with nitrogen gas and foiled. To dissolve the R5 spin labels, a solution made with 100 µL of acetone and 15 mg of sodium iodide was also purged with nitrogen gas and vortexed with the R5 spin labels. The two tubes of mRNA were mixed with 20 µL of purged acetonitrile, 22.4 µL of autoclaved water, and 200 µL of TE (Tris-EDTA) buffer. The R5 mixtures were then combined and vortexed with the mRNA solutions. After centrifuging the two combined R5 and mRNA solutions at 18000g for 10 minutes, they were mixed well by pipetting up and down the solutions. The two resulting solutions were foiled and placed on a spinning rotor at

Mice bioassay is based on that PSP is free soluble in acid solutions and keep stable in heated acid solutions. When pH is between 2 to 3, PSP is extracted after 5minutes boiling, injected to mice enterocoelia. After that, the tic paralytic symptom will happen to mice. Finally die. According to the dead time of mice, judge the toxicity. The principle of physical and chemical analysis is that toxin molecules are oxidized by alkaline then become fluorescence substance or colored substance. Then tested by ultraviolet or fluorescence detection system. HPLC is frequently used. With the most promotional value is immunocytochemical method. PSP is micromolecule and dosen’t have immunogenicity. So it should be linked to marcromolecular carriers, making it to complete antigen. Usually adopt small dose and long period immune scheme to produce CPV McAb. This method has a low demand to sample pretreatment and it’s simple and

An important aspect to producing synthesized EPO is the use of mammalian cells. EPO contains 40% carbohydrates which are important to the stability and biosynthesis of recombinant EPO (5). In 1984, EPO was able to be cloned and synthesized for use by using recombinant DNA technology (1, 3, 4, 5). The biological properties of synthesized EPO are very similar to the original hormone found naturally in the body (3). The importance of the mammalian cell carbohydrate composition allowed for the carbohydrate portions of recombinant EPO to be almost identical to the carbohydrate portions of native EPO (3). Success in creating synthetic EPO on a large scale that mimics native EPO in humans allowed for the implementation of synthesized EPO for medicinal purposes.

Campbell and Farrell define proteins as polymers of amino acids that have been covalently joined through peptide bonds to form amino acid chains (61). A short amino acid chain comprising of thirty amino acids forms a peptide, and a longer chain of amino acids forms a polypeptide or a protein. Each of the amino acids making up a protein, has a fundamental design that comprises of a central carbon or alpha carbon that is bonded to a hydrogen element, an amino grouping, a carboxyl grouping, and a unique side chain or the R-group (Campbell and Farrell 61).

Different techniques and principles for protein extraction and characterization were demonstrated in this experiment. Various proteins were extracted from different sources: 1.67 g yeast invertase, 1.03 g egg white albumin, and 5.15 g of milk casein. Activity assay for invertase was performed using Benedict’s test and the enzymes inverting action on sucrose was confirmed. Warburg-Christian Method and Bradford Assay were also employed to determine the protein concentration in the albumin and the casein samples. The concentrations for the albumin and casein samples were found to be 0.519 and 0.327 mg/mL, respectively based on Warburg-Christian Assay; and 6.5x10-3¬ and 1.9x10-2 mg/mL
