Thank you all for coming to this lecture. Over the course of my career , I have seen many wonderful scientific ( development ) , but none are as game-changing as genome editing. I am full of (excite) about the possibilities this scientific advance can bring and I hope to share my excitement with you today. As many of you may already know, (gene) play a critical role shaping our lives. Everything from the colour of our eyes to our talent for maths ( depend )on genes. The complete set of genes inside a cell or a living being is called a genome. Our own personal genome carries all the information (need) to make us grow and develop.It also contains information that helps determine our lifespan and (affect) our chances of (contract) certain diseases. Some people, for example, carry a gene that makes them more likely (catch )a certain virus or develop a particular form of cancer. Geneticists (try) to identify which genes relate to which diseases , as they believe genome editing is an effective means of disease treatment and prevention. It allows geneticists to make changes to the genome by (correct), adding, deleting or replacing specific parts of the genetic material. In the near future, geneticists hope to apply this technology to treat a wide range of health problems. Soon we may be able to use such treatments (restore) a blind person's vision or give someone who was born deaf an excellent sense of hearing. (ultimate) , this new technology might even make possible to prevent diseases from ever developing by correcting abnormal genes early on. Genome editing, (serve) as a new weapon in the fight against diseases , will lead to a fundamental change in our approach health care. As the technology continues (develop) at a fast pace, however, questions arise about how to use it (appropriate). Should we restrict our use of this technology to the treatment and prevention of diseases Should we prohibit geneticists using it to enhance healthy bodies One day soon we will be able to use genome editing to increase the human (resist) to colds and flu, to make people taller, to help their muscles develop faster, to sharpen all of their (sense) or (make) them more intelligent.We will also be able to select specific (characteristic) for children before they are born, (create) what some have called “designer babies”. However,is this a good thing What consequences might it have Philosophers, geneticists and government officials have all started to wrestle such moral issues. We have to figure out how to keep the technology from running wild. This (mean) putting appropriate controls in place to make sure that genome editing will work our advantage. them, genome editing could be as dangerous as a car out of control. There is still much to (explore) and debated on the subject of genome editing. Despite the public argument over this technology, its possibilities have been creating much excitement throughout the entire medical community and beyond. Without doubt, genome editing is one of the greatest (invention )in the history of science. Thank you for listening.
