Question

Gene banks comprise of
a. Seed banks, orchards, tissue culture and cryopreservation
b. Seed banks, tissue culture and cryopreservation
c. Seed banks, and cryopreservation
d. Tissue culture and cryopreservation

Answer 1

Hint: We can say that a natural category of biorepository (which means abiotic materials repository) that are formed to preserve genetic material. Since agricultural biodiversity is essential, we usually make an effort to protect it. Countless numbers of plant genetic resources of major crop plants and their crop wild relatives are available in the gene bank.

Complete answer:
In the case of plants, preservation is thru by in vitro stowage. It includes the process of freezing and cuttings the materials from the plant and stocking these materials. Besides, in the case of animals, this is completed by the freezing of the sexual cells like sperm and eggs in zoological freezers until they need them. The water tanks are made to stay under controlled conditions on taking the corals, fragments, and storing them. In general, one can define a Gene bank as a sort of biorepository which includes the preservation of genetic material for usage in the future.
Such gene banks typically consist of the materials like a seed bank, tissue bank, cryopreservation, pollen bank, field gene bank, etc.

Hence, the correct answer is option (B).

Additional information:
Gene bank involves a variety of methods in preserving the genetic material. Some of them are:
- To freeze the required materials at -196° Celsius in liquid nitrogen.
- Placing the materials in artificial ecosystems.
- Placing them under the controlled nutrient mediums.

Note: As we know, there are several gene banks throughout the world. One of the famous gene banks is the Svalbard Global Seed Vault being. Genesis is a standard website through which the database of the largest gene banks in the world can be queried.
