  2. Industrial process

  3. Agricultural process

  4. Aquatic process
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

White (also called gray) biotechnology involves industrial processes such as the production of new chemicals or the development of new fuels for vehicles, the use of cells, natural organisms and bio-organic compounds to synthesize materials, instead of petrochemicals or substitution of enzymes for caustic reagents.

Penicillin was used in ............

  1. I$^{st}$ world war
  2. II$^{nd}$ word war
  3. Both I$^{st}$ & II$^{nd}$ world war

  4. None of the above
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Penicillin made a difference during the first half of the 20th century. Penicillin helped reduce the number of deaths and amputations of troops during World War II. According to records, there were only 400 million units of penicillin available during the first five months of 1943.

Product  of biotechnology is

  1. Transgenic crop

  2. Humulin

  3. Biofertilizer

  4. All of the above
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Biotechnology uses cellular and biomolecular processes to develop technologies and products that help improve our lives and the health of our planet. Plants and animals can be improved by selectively breeding for particular traits or by genetic modification. Beneficial traits can be identified visually or by DNA profiling. Gene modification or transgenesis are used to produce therapeutic human proteins in cells or whole organisms. The cell or organism used depends upon how large and complex the protein is. For example, human insulin. Biotechnology improves crop insect resistance, enhances crop herbicide tolerance and facilitates the use of more environmentally sustainable farming practices.

The drug streptomycin inhibits the process of

  1. Prokaryotic translation

  2. Eukaryotic translation

  3. Prokaryotic transcription

  4. Eukaryotic transcription
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation
When purifying protein from a biological extract, streptomycin sulfate is sometimes added as a means of removing nucleic acids. Since it binds to ribosomes and precipitates out of solution, it serves as a method for removing rRNA, mRNA, and even DNA if the extract is from a prokaryote
So, the correct answer is 'Prokaryotic translation'

Two bacteria commonly employed in genetic engineering are

  1. Rhizobium and Diplococcus

  2. Escherichia and Agrobacterium

  3. Nitrobacter and Azotobacter

  4. Nitrosomonas and Klebsiella
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Genetic engineering is the process of modifying the genetic makeup of an organism. In this, specific genes from one organism are transferred into the chromosome of another organism. Two bacteria commonly employed in genetic engineering are Escherichia and Agrobacterium. Escherichia is widely used in because it is easy and inexpensive to grow. It is easy to manipulate the genome of Escherichia. Agrobacterium is used because of its ability to transfer genes to plants and fungi due to presence of Ti plasmid.

Thus, the correct answer is 'Escherichia and Agrobacterium.'
