Question

Ideal host for the amplification of DNA molecule is
(a) Viruses
(b) Plants
(c) Bacteria
(d) Animals

Answer 1

Hint: DNA is deoxyribonucleic acid that contains hereditary materials in humans. It contains genetic code and helps in the storage of information. It passes genetic materials from parents to offspring and regulates the construction of proteins that are necessary for the cell to perform all its functions.

Complete answer:
Bacteria is the ideal host for the implication of a DNA molecule. It is because of their short doubling time and tools for manipulating the bacteria. Shows the availability of extensive knowledge. The short doubling time provides enough amplified DNA and is advantageous in a short period. The tools help in amplifying the variety of DNA molecules. Bacteria is a single-celled, microscopic organism that lives in the soil and ocean or inside the human gut. Bacteria are prokaryotic organisms that are very few micrometers in length and have numerous shapes. They show a symbiotic and parasitic relationship with both plants and animals. Pathogenic bacteria cause infectious diseases which include Cholera, syphilis, leprosy, and bubonic plague. Tuberculosis is spread by fatal bacteria which causes respiratory infections and kills about 2 million people per year.

Additional information:
Viruses: A virus is an infectious agent that is submicroscopic and replicates inside the living cells of an organism. It affects all types of life forms from animals to plants which include some microorganisms like bacteria and archaea. The host cell is forced to rapidly produce thousands of identical copies of the original virus when it gets infected. Virus constitutes the genetic material which are long molecules of DNA and RNA encoded by the structure of proteins. The protein coat, capsid protects the genetic material.
Plants: They are multicellular organisms that are photosynthetic i.e. they prepare their food by the process of photosynthesis in presence of sunlight. The cell wall of the plant is composed of polysaccharides cellulose, pectin, and hemicelluloses. calcium provides growth and nutrition to the plant as well as in cell wall deposition. It neutralizes the cell’s acid.
Animals: They are multicellular eukaryotic organisms that form the kingdom of Animalia. They consume organic materials, breathe Oxygen, and can move easily. They reproduce sexually and can grow from a sphere of cells known as blastula during embryonic development.

So, the correct answer is 'Bacteria'.

Note:
Bacteria have been on the planet for about 3.5 billion years and our oldest known life form on earth. Humans eat some bacteria and most of them are good. They were discovered in 1674 and have a unique shape and are single-celled. Bacteria occur everywhere from bread, yogurt to the inside of humans.
