They get shorter each time a cell divides, until a cell cannot divide any more and dies. 可知,端粒是特殊的DNA 的序列,可以阻止染色体中的DNA 分裂。每次细胞分裂时,它们都变得更短,直到细胞不能分裂任何一个细胞。可知,“they”指的是Telomeres. 故选A。 14. 推理判断题。由第六段Telomeres shortened ...
Later, they discovered each time a cell divides, its telomeres become shorter, like the ticking of a biological clock.(他们称之为“端粒”。 后来,他们发现细胞每分裂一次,端粒就会变短,就像生物钟的滴答声一样。)”可知,上文提到了Elizabeth Blackburn和Jack Szostak解开了细胞分裂时染色体如何保持不变的...
根据第六段最后两句Telomeres shorten or become damaged every time a cell dividesand cell replication stops altogether when telomeres become too short Therefore, shorter telomeres havebeenlinked with high risks for some diseases.可知每次细胞分裂的时候,粒端染色体就会变短。而细胞分裂是一直发生的,也就是...
根据第六段最后两句“Telomeres shorten or become damaged every time a cell divides and cell replication stops altogether when telomeres become too short. Therefore, shorter telomeres have been linked with high risks of some diseases.”可知,每次细胞分裂的时候,端粒就会变短。而细胞分裂是一直发生的,也...

They get shorter each time a cell divides, until a cell cannot divide any more and dies. Several factors have been found to shorten telomeres, including smoking, radiation and psychological stresses such as being treated badly when young and taking care of a chronically ill person. In this stu...
What is cell cycle, and what occurs at each stage? The process by which a cell divides into two daughter cells is called: A. interphase B. mitosis C. cell division D. metaphase What are two cell populations in the body that do not routinely undergo cell division?

Later, they discovered each time a cell divides, its telomeres become shorter, like the ticking of a biological clock.T hese discoveries won Blackburn and Szostaka the Nobel prize in 2009. Hype soon followed and researchers began piling into the field. However, as we find out more about ...
