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 ...
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...
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...
2.when checkpoint controls over cell division are damaged ,a cell repeatedly divides,forming a mass of cell called a ___3.checkpoint controls consist of proteins that detect mistakes and damage and quickly halt the cell cycle until repairs are made.when this occurs the cell is said to be ...
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...
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...
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? Which type of cell division answers somatic growth in...
“一个能够管理一个国家和世界的人一定是一个受过良好的教育而且能成功地支撑起自己家庭的人。”正如 中国 儒 The family exists in the human throughout history all societies, no matter is in the past or in the present, the family was society's cell, was a social inalienable part, also was a...
aconditioning solution 适应的解答[translate] ain the process damage the DNA of the cell so that when it divides, the new cell carries the mutant DNA that in turn passes along to the next cell when it divides. 在处理损伤细胞的脱氧核糖核酸,以便,当它划分,新的细胞运载反过来通过对下个细胞的突...
Lead investigator of the study John Nguyen said healthy telomeres are long and strong, but shorter, fraying telomeres are a hallmark of aging and are linked to diseases like diabetes, cancer and heart disease. Telomeres shorten every time a cell divides into two, which happens with growth and ...
