HORTICULTURE

Detailed explanation-1: -A transgenic, or genetically modified, organism is one that has been altered through recombinant DNA technology, which involves either the combining of DNA from different genomes or the insertion of foreign DNA into a genome.

Detailed explanation-2: -Practices used in traditional plant breeding may include aspects of biotechnology such as tissue culture and mutational breeding. Transgene: A gene from one organism inserted into another organism by recombinant DNA techniques.

Detailed explanation-3: -Recombinant DNA molecules are sometimes called chimeric DNA because they can be made of material from two different species like the mythical chimera.

Detailed explanation-4: -Genetic Engineering For example, genetic engineering may involve adding a gene from one species to an organism from a different species to produce a desired trait.

Detailed explanation-5: -Insertion of genes into such a large DNA molecule is accomplished via small insertion vectors, as described previously for vaccinia. Viral and insertion vector DNA are simultaneously introduced into insect cells by direct uptake using calcium phosphate.
