The lipase gene sequence from Alcaligenes sp. JG3 was translated into amino acid sequence using two methods‚ manual translation and ExPASy online software. By manual method‚ amino acid sequence was obtained via codon translation one by one as shown in Figure IV.7. The sequence reference used is the lipase from A. faecalis MOR02 due to having high similarity with the lipase sequence from strain JG3 during CLUSTAL alignment and the alignment of the deduced amino acid with the referred sequence was

The experiment’s objectives were to synthesize alum‚ test for various ions in alum‚ and form crystals in aqueous alum solution. The alum was synthesized from aluminum foil and run through a filtration system to isolate the alum. 2 Al(s) + 2 KOH + 22 H2O + 4 H2SO4 → 2 KAl(SO4)2●12H2O(s) + 3 H2(g) Its composition was analyzed using two precipitation tests and two flame tests. Three methods for growing crystals were then set up for observation next lab. Theoretical yield and percent yield: The theoretical

In this section we will analyze which steps were the most effective ones in recovering LDH (percent yield) and in purifying LDH (fold purification). As we can see looking at the Total Protein column on Table 3‚ the most effective step with regard to the percent of remaining protein removed was affinity chromatography because it was able to remove 98.6% of the remaining proteins. In comparison to 81.93% removed during the 65% ammonium sulfate precipitation and 81.3% during the size exclusion

to evolve. Formal and Non Formal Education has basic differences. Formal education is classroom-based‚ accompanied by trained teachers. Informal education happens outside the classroom‚ in after-school programs‚ community-based organizations‚ museums‚ libraries‚ or at home. Both formal and informal education settings offer different strengths to educational outreach project. After-school programs offer a different kind of environment‚ where ones activities don’t need to be as formal and once can

Introduction: Bacteria are microscopic‚ single-celled organisms. Their genetic information is encoded in one large chromosome. It can also be found in plasmids which are small circular pieces of DNA that contain important genetic information for the growth of bacteria. In nature‚ this information is often a gene that encodes a protein that will make the bacteria resistant to an antibiotic. The reason for this protein being made within the bacteria is because of how bacteria usually grow in the same

“The Synthesis of Zinc Chloride”‚ what a peculiar name for a lab that does not even involve synthesis. Synthesis‚ by definition‚ is when two elements are combined in a chemical reaction‚but that is not the case. In this lab we are combining zinc‚ an element‚ and hydrochloric acid‚ a compound‚ but combining a compound and an element is not synthesis‚ it is single replacement. We are taking zinc and hydrochloric acid and making zinc chloride and hydrogen‚ a single replacement‚ but what occurred during

Figure 6: Imatinib The first imatinib drug synthesis was done by Zimmermann (figure 7) in 1993‚ he used a chain of the reaction to reach to imatinib but the important part is that both guanidinium nitrate 7 and aminopyrimidine 8 are precipitated from the respective reaction mixtures by the addition of Figure 7: imatinib synthesis by Zimmermann insolubilizing solvents‚ so we got a condensation reaction between guanidinium salt 7 with enone “9” to form the aminopyrimidine “8” then “8” is
