Without doubt For years, scientists have been working to (2) _____ specific genetic markers that are connected with a long lifespan. Until recently, only two such markers were known to the scientific community(科学界). Genes play a critical role in overall health(整体健康). Every (3) _____ in the human body contains genetic information. Everything from the ageing process(衰老过程) to the development of deadly diseases, such as cancer, is tied to(与...密切相关) an individual’s genetic make-up(遗传构成). identify cell However, scientists have long been (4) _____ the question about which genetic markers indicate(表明，象征) a short or long lifespan. The discovery by the research team may quicken the (5) _____ of the study on genes and human lifespans, and eventually help answer this question. Scientists say that locating(定位) these sixteen genetic markers will greatly improve their understanding of how genes (6) _____ lifespans. pace wrestling with affect These genetic markers may eventually function as a (7) _____ of targeting(针对) the specific genes connected with lifespans. This could significantly(显著地) enhance people’s chances of living to a ripe(成熟) old ages. According to some scientists, it could make a (8) _____ change to the future of human life. fundamental means As we all know, genes play a crucial role in shaping our lives.
