Why is it that the line of treatment for a genetic disease is different from infectious diseases?
If a person is born with a hereditary disease, can a corrective therapy be taken for such a disease? Gene therapy is an attempt to do this. Gene therapy is a collection of methods that allows correction of a gene defect that has been diagnosed in a child/embryo.
Many proteins are secreted in their inactive form. This is also hue of many toxic proteins produced by micro organisms. Explain how the mechanism is useful for the organism producing the toxin.
Explain with the help of one example how genetically modified plants can:
(a) Reduce usage of chemical pesticides .
(b) Enhance nutritional value of food crops
Gene therapy is an attempt to correct a genetic defect by providing a normal gene into the individual. By this’the normal function can be restored. An alternate method would be to provide the gene product (protein/enzyme) known as enzyme replacement therapy, which would also restore the function. Which in your opinion is a better option? Give reason for your answer.

Transgenic animals are the animals in which a foreign gene is expressed. Such animals can be used to study the fundamental biological process, phenomenon as well as for producing products useful for mankind. Give one example for each type.
Explain with the help of one example how genetically modified plants can:
(a) Reduce usage of chemical pesticides .
(b) Enhance nutritional value of food crops
