※ 引述《CGHS13 (.......)》之銘言： : Telomerase is an enzyme that is produced only in cells that are actively : dividing. For this reason it is generally absent from body tissues in adults : Bone marrow is an exception to this rule, however, since even in adults, bone : marrow cells continually divide to replace old blood cells. Cancers are : another exception, because their cells are rapaidly dividing. : A. Telomerase is the only enzyme that is present in cancerous cells but : absent from cells that are not activly dividing. : B. in children, the only body tissues from which telomerase is absent are : those ins which cells are not rapidly dividing. : C. The presence of telomerase in bon marrow is no indication of bone marrow : cancer. : D. Cancer of the bone marrow develops more rapidly than cancer growing in any : other kind of adult tissue. : E. The level of telomerase production is always higher in cancerous tissue : than in noncancerous tissue. : the information provided most strongly supports which if the following? : the answer is C : 不懂....? : why not E? : 題目說的不是 Telomerase 只存在於分裂活躍的細胞中 : 因為這個原因所以很少產生在成人體內 : 但是bone marrow 與 Cancer 是例外 : 存在於bone marrow 是因為bone marrow cell 不斷分裂以替代老的紅血球細胞 : cancer 是因為他們的細胞快速在分裂 : 所以 C ?... C是無法挑錯的答案因為他提到骨髓跟cancer都是例外，所以骨髓有T酵素並不代表得了骨髓癌 E不對因為他只提到T酵素會在細胞分裂的情況出現沒有提到分裂越快的地方就越多T酵素，所以有可能在骨髓的地方T酵素更多 -- 喜歡跟愛是不一樣的喜歡是盪鞦韆可以自得其樂不需要別人的回應愛是翹翹板需要一個人坐在對面與你互動貼近你內心的感覺... -- ※ 發信站: 批踢踢實業坊(ptt.cc) ◆ From: 140.112.4.234
