A B Figure 1 The postgraduate student, Vanessa, cloned her gene of interest into two different vectors; pUC18 and pZERO®-1, and transformed the competent cells with the recombinant vectors. After that, she plated them on the antibiotic plates and incubated her samples for 18 hours. The next day, she realized that the plates were not labelled. (i) Based on the observation above, can you identify which plate is carrying the recombinant pUC18 and pZErOⓇ-1, respectively? (ii) Why are there small colonies surrounding the big colonies in Figure 1 (A)? Explain your answer in detail. (iii) Do you think all the colonies present on the plates in Figure 1 (B) contain the gene of interest? Describe the selection procedures for recombinant pZERO®-1.

Q11) Explain, using the pCR 2.1 vector, what we would see if we try to grow cells on a plate with ampicillin and Xgal in each of these scenarios:a) transformation not successful (meaning the plasmid did not go inside the bacteria)b) transformation was successful, but no insert in LacZ gene (plasmid went in the bacteria but there was no inserted DNA in the LacZ gene of the plasmid)c) transformation and the ligation reactions were successful (got the plasmid in, and the plasmid is carrying extra DNA in the LacZ region, yay)

Ms. Carla was required to clone three different genes (Gcne 1, Gene 2 and Gene 3) into PUC18. After generating three recombinant plasmids, she transformed them into the Escherichiu coli host cells and plated them on the LB agar plates containing X-gal. After a 16-hour incubation peried, she obtained different outcomes for all of her three genes of interest. Gene 1 plate: No colonies ut all Gene 2 plate: All blue colonies Gene 3 plate: All white colonies Explain the results obtained for cach plate with clear justification.

In a use-dilution test, for microorganism X, we evaluated 3 different disinfectants T1, T2 and T3 with the following disinfectant dilutions: 1/10, 1/100, 1/1,000 and 1/10,000. T1 killed the microorganism up to the dilution of 1/100; T2 killed the microorganisms up to the dilution of 1/10,000 and T3 killed the microorganisms up to the dilution of 1/1,000. Rank the disinfectants in the order of their strength with the strongest being first, for disinfecting contaminations with microorganism Xor alternatively are they all equally effective?

(a) Suggest an advantage and a disadvantage of DNA vaccines. (b) Briefly explain how the DNA vaccine can stimulate the production of anti-COVID-19 antibodies in vaccinated individuals. (c) Design an indirect ELISA for Sam to screen for anti-COVID-19 antibodies in the volunteers. Describe in detail how the immunoassay should be performed.
