Which of the following system can be utilized for glycosylation of peptides expressed using recombinant DNA technology?
Large bacterial fermenters
Small bacterial fermenters
Normal bacterial bioreactors
Mammalian cell line
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

3/4 r2h
2r2h
4/3 r2h
Which of the following food crops has recently been genetically engineered to obtain edible vaccine to develop immunity against hepatitis B?
Banana

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
