All of the following biotechnological advances are possible except one. that is the a) reproductive cloning of humans. b) production of transgenic animals. c) use of gene therapy to treat diseases. d) production of disease-resistant agricultural crops.

A) reproductive cloning of humans.

Biotechnology is the broad discipline of biology in which living organisms and their products are manipulated in such a way that they can be utilized for the purpose of human society. The antibiotics, hormones, industrial products and genetically modified organisms are the products of biotechnology.

Reproductive cloning of humans cannot be considered as the advantage of biotechnology because of the following reasons:

1. Difficulty in establishing identity:  We human beings differ from each other on the basis of differences in the physical and genetic features. If the clones are developed than it would become difficult to assign identity to a person.  

2. It is against ethics: The human beings and other organisms are natural creation the human induced technology to develop a life can be against the nature's regulation. Therefore, human cloning is against the ethics.

3. It can be costly and technology efficient process: The technology used to create human clone can be expensive and time consuming.

the answer is false?
