Why are genetically modified organisms produced ?Explain the purpose and advantages .

Explanation

Genetically Modified Organisms:
(i)Genetic modification refers to the alteration or manipulation of genes in the organism using rDNA techniques in order to produce the desired characterisitcs.
(ii)The DNA fragement inserted is called transgene. (iii)Plants or animals expressing a modified endogenous gene or a foreign gene are also known as transgenic organism. Advantages: (i)The transgenic plants are much stable,with improved nutritional quality,resistant to diseases and tolerant to various environment conditions.
(ii)Similarly transgenic animals are used to produce proteins of medicinal importance at low cost and improve livestock quality. eg Golden Rice is a genetically modified Rich which can produce beta carotene.
