Biofortification refers to the breeding of crops to increase their nutritional value. The crops produced
through biofortification method are always rich in nutrients like iron, zinc and Vitamin A. for example, Golden rice was produced using the method of biofortification. This rice is rich in beta-carotene and provides vitamin A to the children.

The morphology of the chromosomes can be distinctly studied at metaphase stage of cell division because at this stage chromosomes are in highly condensed state and become thicker and well arranged. The following structures are observed in a typical chromosome: Chromatid, Chromonemata, Primary constriction (centromere), Secondary constriction (nucleolar organizer), satellite, telomere, and chromosmere.

Protein electrophoresis and Western blotting are both methods used to identify specific proteins in a sample or solution. Western blotting, also known as immunoblotting or protein blotting, is a core technique in cell and molecular biology. In most basic terms, it is used to detect the presence of a specific protein in a complex mixture extracted from cells.

Correct Option: B

Calyptrogen is a layer of rapidly dividing cells at the tip of a plant root, from which the root cap is formed. It occurs in grasses and many other plants. The root cap is formed by several layers of cells that envelop the root tip externally. This covering of cells, of which the outermost ones are dead, envelops and protects the growing tip very much as a thimble protects the finger.

Zika virus (ZIKV) is a member of the virus family Flaviviridae is spread by daytime-active Aedes mosquitoes, such as A. aegypti and A. albopictus. Its name comes from the Zika Forest of Uganda, where the virus was first isolated in 1947. Zika virus is related to the dengue, yellow fever, Japanese encephalitis, and West Nile viruses.
