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.

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 $\mathrm{N}_{2}$ 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.
