Q & A

What is CRISPR technology?

CRISPR (Clustered Regularly Interspaced Short Palindromic Repeats) technology is a revolutionary gene-editing tool that allows scientists to edit DNA sequences directly. It has the capability to target and cut DNA at precise locations, enabling specific edits to be made.

Why did the CRISPR technology become a hot topic in the biotech community?

CRISPR technology became a hot topic because it offers a relatively simple, efficient, and cost-effective way to edit genes, which has broad applications in research, medicine, and agriculture.

What was the controversial event involving CRISPR technology mentioned in the script?

The controversial event was the announcement by Chinese scientist Dr. He Jiankui that he had successfully created the first gene-edited babies, twin girls, to be resistant to HIV. This was met with widespread criticism due to ethical concerns and potential health risks.

What was the outcome of Dr. He Jiankui's experiment with gene-edited babies?

Dr. He Jiankui faced severe backlash from the scientific community, his research was halted by the Chinese government, and he was sentenced to three years in prison for his unauthorized experiments.

What is the CCR5 gene mentioned in the script, and why was it targeted for editing?

The CCR5 gene codes for a protein on the surface of white blood cells that HIV viruses typically recognize and use to enter the cells. By editing the CCR5 gene, the aim was to make the cells unrecognizable to HIV, thereby providing resistance to the virus.

What are some of the potential applications of CRISPR technology mentioned in the script?

CRISPR technology has potential applications in creating drought-resistant crops, extending the freshness of fruits, making livestock resistant to diseases, and treating various medical conditions such as sickle cell anemia, certain eye diseases, and beta-thalassemia.

What are the ethical concerns raised by the use of CRISPR technology on human embryos?

The ethical concerns include the potential for unintended consequences, the possibility of creating 'designer babies,' and the long-term genetic impact on the human gene pool. There are also concerns about the technology being misused for selfish purposes.

How does the World Health Organization (WHO) approach the regulation of CRISPR technology?

The WHO has initiated efforts to provide guidelines for evaluating the use of CRISPR on heritable human genes. It emphasizes the need for clear regulations on the use of this technology, considering the ethical, social, and safety implications.

What are the potential risks associated with the misuse of CRISPR technology?

Misuse of CRISPR technology could lead to unforeseen genetic mutations, exacerbate social inequalities, and potentially create new biological threats if used irresponsibly.

What is the current status of CRISPR technology usage in the world?

The use of CRISPR technology remains a subject of debate. While it holds immense potential for medical and agricultural advancements, its application in humans, especially in germline editing, is highly regulated due to ethical and safety considerations.

What is the challenge that humanity faces with the advancement of CRISPR technology?

The challenge is to balance the potential benefits of CRISPR technology with the ethical and safety concerns. It requires responsible decision-making and the establishment of clear international guidelines to govern its use.
