Identify a micro-organism that can produces biomass of protein.
1 Monoscus purpureus
2 Aspergillus niger
3 Methylophilus methylotrophus
4 Trichoderma polysporum
Explanation:
The methylotrophic bacterium Methylophilus methylotrophus hydrolyses urea to ammonia using a cytoplasmic urease. During growth in continuous culture under various nutrient limitations urease was induced by urea and short- chain amides and repressed by excess ammonia.

Biological Classification
258431
Identify the plasmid.
1 Eco RI
2 pBR 322
3 AIU I
4 Hind III
Explanation:
pBR 322, in order to link the alien DNA the vector needs to have very few recognition site of the commonly used restriction enzymes.
Karnataka CET-2004
Biological Classification
258432
Which of the following statements is right?
1 Diatoms produce basidiospores.
2 Heterocysts are found in Nostoc.
3 Fronds are found in Bryophytes.
4 Multiciliate sperm are found in Angiosperm
Explanation:
Nostoc species are filamentous cyanobacteria. These organisms have the ability to fix atmospheric with the help of enzyme present in heterocyst. Basidiospores are produced by basidiomycetes. Fronds are found in pteridophytes. Cilia are absent in sperm of angiosperms.
