Q & A

What is CRISPR technology?

CRISPR is a gene-editing technology that allows scientists to precisely alter DNA by cutting and replacing specific parts of the genetic code, similar to a 'find and replace' function in a word document.

How does CRISPR work?

CRISPR works by using an enzyme called Cas9, which acts like a pair of super-precise scissors to cut DNA. The enzyme is guided to the correct spot by guide RNA, which ensures the edit happens at the right place in the DNA.

Where did CRISPR technology originate?

CRISPR technology originated from bacteria, which use it as a defense mechanism against viruses. Bacteria store pieces of viral DNA in their own genetic code, which allows them to recognize and fight off the same virus in the future.

What are some potential medical applications of CRISPR?

CRISPR has the potential to cure genetic diseases such as beta-thalassemia and cystic fibrosis. It is also being explored for cancer therapies and HIV treatments, where it could directly remove the virus from a patient's DNA.

How can CRISPR help in agriculture?

CRISPR can be used to improve crop yields and create drought-resistant plants. For example, genetically modified rice has been developed to increase harvests, and CRISPR could help create crops that require less water to grow.

What role does CRISPR play in biotechnology?

In biotechnology, CRISPR helps scientists understand how genes function in humans, animals, and plants. It can also be used to resurrect endangered species and modify microbes to produce eco-friendly biofuels and chemicals.

What are the safety concerns associated with CRISPR?

One concern is the possibility of off-target effects, where CRISPR might unintentionally alter the wrong part of the DNA, leading to new diseases or other unintended consequences. There is also the risk of unintended genetic changes having long-term effects.

What ethical dilemmas are raised by CRISPR technology?

CRISPR raises ethical concerns about 'designer babies,' where parents could choose specific genetic traits for their children. It also raises questions about fairness, as the technology may be more accessible to the wealthy, widening social inequality.

How could CRISPR technology impact social inequality?

If CRISPR technology is only accessible to wealthy individuals or nations, it could exacerbate social inequality. Wealthier people could potentially afford genetic enhancements, leading to further divisions between the rich and the poor.

What are the potential risks of gene editing in humans?

Gene editing in humans carries the risk of unintended genetic changes that could result in new diseases or conditions. There is also concern about the possibility of creating 'designer babies,' which could lead to ethical and societal problems.
