10、 Answer the questions below each text by choosing A, B, C or D. Mark your answers on the ANSWER SHEET. (40 points)Text 1 Studying the DNA of 300 mice has flagged up genes which have been linked to hereditary (遗传的) sight loss for the first time. Researchers say because mices genes are so similar to h
11、umans, their findings could lead to the treatment of more genetic diseases.Scientists at the University of California, Davis studied information from a data bank of mices genetic material. They found 347 genes linked to eye problems, with just 86 of them having been studied in the past.Only around 5
12、0 to 75 percent of hereditary eye diseases in human can be explained with present science. The researchers believe these hundreds of new genes found in mice could be a key to explaining-and therefore being able to treat the other 25-50 percent.“This is extremely valuable for people with hereditary e
13、ye disease,” said researcher Professor Ala Moshiri. “All researchers are going to start using these data. In the past, we knew the problem was there but we didnt know where to look. Now eye centers can call back patients and screen them for these new genes. We expected that more and more of these ge
14、netic diseases will be treatable.” Also, the fact is that more than 60 percent of eye problems at birth are ones resulting from the babys parents!Thanks to data from the International Mouse Phenotyping Consortium (IMPC), which is trying to work out what every single gene in a mouse is responsible fo
15、r, with the aim of translating it to humans, scientists are moving closer to figuring out all genetic causes of blindness. To do this, scientists separate a single gene from other ones at a time and then observe what effect it has on the mouse for a long time. This has so far been done more than 7,000 times and has achieved great success. Researchers are now working alongside eye care centers in Texas and Iowa in order to compare the mices genes
