Q & A

What is the significance of DNA in shaping who we are?

DNA contains billions of codes that form not only humans but also all living creatures in the world. It is the fundamental component that determines our traits and characteristics.

What is the process known as 'editing' or 'modifying' DNA?

Editing or modifying DNA refers to the scientific technique of altering the genetic code within an organism, which can potentially change its physical and functional attributes.

What is CRISPR-Cas9 and how is it related to DNA editing?

CRISPR-Cas9 is a revolutionary gene-editing technology that allows scientists to edit genes accurately, efficiently, and inexpensively. It is often described as 'molecular scissors' for cutting and modifying DNA sequences.

Can we theoretically design a perfect human through genetic engineering?

In theory, yes, we could potentially design a human with enhanced physical appearance, intelligence, and other desirable traits by modifying their genetic code.

What are some of the ethical concerns associated with genetic engineering of humans?

Ethical concerns include the potential for misuse of technology, violation of existing ethical codes and laws, and the unforeseen consequences of altering the human genetic code.

What was the controversial case involving gene-edited babies in China?

The controversial case involved Chinese researchers who claimed to have created gene-edited babies, which sparked global outrage due to the violation of ethical standards and potential legal issues.

How can genetic engineering potentially benefit humanity?

Genetic engineering can benefit humanity by potentially curing diseases, enhancing resistance to infections, and improving overall health and well-being.

What is the potential of genetic engineering in the context of disease resistance?

Genetic engineering could potentially allow for the design of humans with enhanced resistance to specific diseases, thereby reducing the impact of illnesses on the population.

What are the current limitations of applying genetic engineering to create a 'perfect' human?

Current limitations include the complexity of the human genome, the ethical implications of such modifications, and the lack of comprehensive understanding of the long-term effects of genetic changes.

How does the script suggest we should approach the advancement of genetic engineering?

The script suggests that while we have reached unprecedented levels of genetic engineering, we should proceed with caution, keeping in mind the ethical considerations and potential consequences of our actions.
