Researchers say a project begun nearly ten years ago to map the human genome in an effort to figure out the genetic code contained in our DNA will be 90% completed by next year.(1)_______________________.When they hear about DNA,many people may think of some monster movie they saw.As a matter of fact, knowing about DNA is going to enrich our life and improve our health.We should welcome, not fear genetic research.DNA molecules contain about three billion pieces.(2)_______________________.Thanks mostly to new technology,20% of the three billion letter human genome has already been sorted out.The National Institutes of Health says 90% will be completed within a year.And the challenge then will be to understand how the roughly 80 000 genes that reside in the script do what they do,and how they are involved in health and disease.(3)_______________________;genes for breast cancer, cystic fibrosis,and Parkinson’s disease are already under intense study.But just mapping the human genome doesn’t end the journey.Figuring out how to use the map to deliver the cure is the next big job.

1) That's about five years ahead of the schedule and promises to ex-salary new treatment for major diseas.
2) They form genes that provide instructions on how to build the unique thoughts that make up our humanbeing.
3) Reserchers are finding genes can be figure out ..how they function.作者: suesxy 时间: 2011-11-21 20:53

That's about 5 years ahead schedule and promise to ..new treatment for those diseases
The form gense proved instruction .......that make up our humanbeing
Researchers are finding genes faster that they can figure out how they function作者: riverfeng 时间: 2011-11-23 10:48
