Which of the following system can be utilized for glycosylation of peptides expressed using recombinant DNA technology?

• Large bacterial fermenters

• Small bacterial fermenters

To assess the mutation in bacteria, bacteria were inoculated in various aliquots and later on shifted on screening media for selection of mutants. The most important information for assessing mutation would be

• Total number of mutant

• Average number of mutant per aliquot

• Petri plates with single mutant colony

• Petri plates without ant mutant colony

A culture of an E.coli strain that is lysogenic for phase lambda is grown at 32°C. Induction of the prophage from the host chromosome will occur when the culture is exposed to

• 40ºC

• Ultra violet radiation

• Infra-red radiation

• Wild type E.coil culture

Which of the following methods of plant transformation can be used to induce a gene into chloroplast genome?

• Agrobacterium mediated transformation

• Particle delivery system

• Permeabilizatin

• Electroporation

If period of f(x) = sin x is 2$\mathrm{\pi }$, then the period of g(x) = sin (2x) will be:

• $\mathrm{\pi }$

• $2\mathrm{\pi }$

• $\mathrm{\pi }/2$

• $4\mathrm{\pi }$

It is predicted that due to globalwarming there would be rise in level of oceans. If radiusof earth is R and rise in level of water of water is 'h', then the volume of water will be :

• $\mathrm{\pi }$r²h

• 3/4 $\mathrm{\pi }$r²h

• 2$\mathrm{\pi }$r²h

• 4/3 $\mathrm{\pi }$r²h

Which of the following food crops has recently been genetically engineered to obtain edible vaccine to develop immunity against hepatitis B?

Let f:[0, 1] → (0, infinity sign) be a continuous function. Suppose f(0) = 1 and f(1) = 7. Then

• f is uniformly continuous and is not onto. 

• f is increasing and f([0, 1]) = [1, 7]

• f is not uniformly continuous

• f is not bounded

The net direction of force on charge placed at origin as shown in diagram will be in:

• +Y

• -Y 

• +X

• -X

The general procedure for estimation of primary production is the “light” and “dark” bottles method. In an experiment two bottles containing 200 mg/ l of O₂ was incubated in light and dark for seven days. The amount of O₂ estimated after incubation period was found to be 600 mg/ l and 100 mg/ l in light and dark respectively. The net primary production during the incubation period is:

• 400 mg/ l

• 100mL/ l

• 500 mg / L

• 600 mg/ l
