Cultivation of Bt cotton has been much in the news. The prefix Bt means

A
“Barium treated” cotton seeds

B
“Bigger thread” variety of cotton with better tensile strength

C
Carrying an endotoxin gene from Bacillus thuringiensis

D
Produced by “biotechnology” using restriction enzymes and ligases
Solution
Bacillus thuringiensis (or Bt) is a Gram-positive, soil-dwelling bacterium, commonly used as a biological pesticide.
During sporulation, many Bt strains produce crystal proteins (proteinaceous inclusions), called delta endotoxins, that have insecticidal action.
This has led to their use as insecticides, and more recently to genetically modified crops using Bt genes.

Hybridoma technology has been successfully used in

A
Production of alcohol in bulk

B
Synthesis of monoclonal antibodies

C
Synthesis of haemoglobin

D
Production of somatic hybrids

Solution

Hybridoma technology has contributed to virtually all areas of biology and medicine and set the scene for important advances in cell biology and immunodiagnostics. Blood transfusion and transfusion medicine have benefited significantly from the development of hybridoma technology, and this has resulted in the generation of a wide range of monoclonal antibodies to human blood group antigens.

A technology which has found immense use in solving cases of disputed parentage is

A
Monoclonal antibody production

B
DNA finger printing

C
Polymerase chain reaction

D
Recombinant DNA technology

Solution

DNA fingerprinting is a technology that has found immense use in solving cases of disputed parentage.
It is a technology that uses sequences of DNA to identify an individual. This technology was invented by Alec Jeffreys in the year 1984.

C
1917

D
1907

Solution

In 1917, Chaim Weizmann first used a pure microbiological culture in an industrial process, using Clostridium acetobutylicum, to produce acetone, which was urgently needed by the United Kingdom to manufacture explosives during World War I (WWI).
