Text1

Gene therapy and gene based drugs are two ways we could benefit from our growing ___stery of geic scien ___. But there will be others as well. Here is one of the re

___rkable therapies on the cutting edge of geic research that could ___ke their way into ___instream medicine in the ing years.

While it’s true that just about every ___ll in the body has the instructions to ___ke a plete hu ___n, most of those instructions are inactivated, and with good reason: the last thing you want for your brain ___lls is to start churning out sto ___ch acid or your nose to turn into a kidney. The only time ___lls truly have the potential to turn into any and all body parts is very early in a

pregnancy, when so called stem ___lls haven’t begun to specialize.

Yet this untapped potential could be a terrific boon to medicine. Most diseases involve the death of healthy ___lls — brain ___lls in Alzheimer’s, cardiac ___lls in heart disease, pancreatic ___lls in diabetes, to name a few; if doctors could isolate stem ___lls, then direct their growth, they might be able to furnish patients with healthy repla ___ment tissue.

It was incredibly difficult, but last fall scientists at the University of Wisconsin ___naged to isolate stem ___lls and get them to grow into neural, gut, muscle and bone

___lls. The pro ___ss still can’t be controlled, and ___y have unforeseen limitations; but if efforts to understand and ___ster stem ___ll development prove suessful, doctors will have a therapeutic tool of incredible power.

The same applies to cloning, which is really just the other side of the coin; true cloning, as first shown with the sheep Dolly two years ago, involves taking a developed

___ll and reactivating the genome within, resetting its developmental instructions to a pristine state. On ___ that happens, the rejuvenated ___ll can develop into a full fledged ani ___l, geically identical to its parent.

For agriculture, in which purely physical characteristics like milk production in a cow or low fat in a hog have real ___rket value, biological carbon copies could bee routine within a few years. This past year scientists have done for mi ___ and cows what Ian Wilmut did for Dolly, and other creatures are bound to join the cloned menagerie in the ing year.

Hu ___n cloning, on the other hand, ___y be technically feasible but legally and emotionally more difficult. Still, one day it will happen. The ability to reset body ___lls to a pristine, undeveloped state could give doctors exactly the same advantages they would get from stem ___lls: the potential to ___ke healthy body tissues of all sorts, and thus to cure disease. That could prove to be a true “miracle cure.”

21.The writer holds that the potential to ___ke healthy body tissues will

[A] aggravate moral issues of hu ___n cloning.

[B] bring great benefits to hu ___n beings.

[C] help scientists decode body instructions.

[D] involve employing surgical instruments.

22.The word “rejuvenated” (Para. 5) most probably means

[A] modified.[B] re-collected.[C] classified.[D] reactivated.

23.The research at the University of Wisconsin is mentioned to show

[A] the isolation of stem ___lls.[B] the effects of gene therapies.

[C] the advantages of hu ___n cloning.[D] the limitations of tissue repla ___ments.

24.Which of the following is true aording to the text?

[A] The principle of gene therapy is applicable to that of cloning.

[B] The isolation of stem ___lls is too difficult to be feasible.

[C] It is reasonable for all body instructions to be activated.

[D] Cloned ani ___ls will eventually take control of the world.

25.Towards the geic research, the author’s attitude can best be said to be that of

[A] Frustration.[B] Indifferen ___.[C] A ___zement.[D] Opposition.
