Minghao, Mingyu's laboratory partner, was assigned to work on a double-stranded DNA (ds-DNA)sample isolated from a bacteriophage. After DNA sequencing, Minghao discovered that his ds-DNAisolate is composed of 3,462 base nucleotides with 621 G-C base pairs. Minghao needs your assistancein calculating the following:4. total number of base pairs in the ds-DNA isolate5. number of A, T, G, and C base nucleotides in the ds-DNA isolate6. total number of hydrogen bonds in the ds-DNA isolate7. melting temperature of the ds-DNA isolate in °C.

DNA is the genetic material present in our body. DNA structure is right handed double helix in which…

A 2.0kb bacterial plasmid ‘BS1030’ is digested with the restriction endonuclease Sau3A; the plasmid map is depicted in the diagram below and the Sau3A (S) restriction sites are indicated. Which of the following DNA fragments do you expect to see on an agarose gel when you run Sau3A-digested plasmid ‘BS1030’ DNA? a. 250 bp, 450 bp, 550 bp, 1.1 kb, 1.5 kb and 2.0 kb b. 2.0kb c. 250 bp, 400 bp, 450 bp, 500 bp and 550 bp d. 100 bp, 200 bp, 250 bp, 400 bp, 500 bp and 550 bp
Recombinant protein production by a genetically modified Escherichia coli strain is proportional to cell growth. Ammonia is used as a nitrogen source for aerobic glucose respiration. The recombinant protein has the general formula CH1,55O0,31N0,25, while that of the cellular biomass is CH1,77O0,49N0,24. The biomass yield from glucose equals 0.50 g/g, while the recombinant protein yield from glucose corresponds to 20% of the cell yield from substrate.a) How much ammonia is required? What is the oxygen demand? (b) If the biomass yield remains the same, what are the ammonia and oxygen requirements for a wild-type strain of E. coli, with cell biomass of the same elemental composition, but unable to synthesize the recombinant protein? (c) On an industrial scale, cultivation takes place in a continuous fermenter at 28°C and the desired recombinant protein production rate is 7 g/h. Since the viscosity of the culture broth is considerable, the energy input due to agitation cannot be neglected.…
A batch of this DNA is first fully digested by HpaI alone, then another batch is fully digested by HindIII alone, and finally, a third batch is fully digested by both HpaI and HindIII together. The fragments resulting from each of the three digestions are placed in separate wells of an agarose gel, separated by gel electrophoresis, and stained by ethidium bromide. Draw the bands as they would appear on the gel.

In a clinical context, a scientist is working with a viral DNA which is about 24000bps long. There are two known variants of the virus that share almost the same DNA but for a final fragment; with reference to Figure Q2b, the regions A and B are conserved in both variants, while the region C differs and is either 320bps (variant 1) or 380bps (variant 2). The scientist wants to set up a procedure to identify the variant they are dealing with. Viral dsDNA (i) (ii) (iii) Stable region (A) Variable region (C) Figure Q2b Known sequence (B) 5-GACCTCAATGTCCAGCGGTACGCTCATAAA-3' 3'-CTGGAGTTACAGGTCGCCATGCGAGTATTT-5' The scientists want to design a primer to amplify the variable region and to do so, they sequence a small fragment (sequence B) the conserved region close to the variable region C. Why is the scientist targeting a region outside of the fragment of interest? [3] The sequence of the fragment B is reported in Figure Q2b. Suggest a primer that can efficiently target this region and…

As the leading scientist in a biomedical science laboratory, it is a requirement to give advice to your lab assistants when they are having problems with their experiments. What advice would you give to your assistants that are having the following problems: After performing a polymerase chain reaction (PCR) and agarose gel electrophoresis to confirm the presence of the C01 gene of 750bp. 2.1. They observe no band appearing on an agarose gel. What would be your conclusion? 2.2. They observe three bands of different sizes that resemble a smear on the gel. Advice 2.3. They observe a single band on the gel and conclude that the PCR product is an exact copy of the original template DNA. Would you support their condusion? Explain. 2.4. Explain how PCR can be used to detect infectious agents in diagnoses of diseases.
