  • Abstract : selective mechanisms exist in organism and biosphere , which select the cells with less dna injuy and reproduces them . there are two models ; mechanisms 1 and mechanisms 2 , represented respectively b bacteria and mechanolytes of human beings . cells with mechanisms 1 ( e . g . bacteria , generative cells , cancer cells ) can reproduce infinitely , while somatic cells can not . there are deep - going reasons behind the two categories of selective mechanisms . the canceration of the cells is a degenerating process from mechanisms 2 to mechanisms 1
    摘要生物界存在一類篩選機(jī)制,它將dna損傷較小的細(xì)胞篩選出來(lái),產(chǎn)生后代.主要有兩類模式機(jī)制1和機(jī)制2 ,分別以細(xì)菌和人的成纖維細(xì)胞為代表,那些具有篩選機(jī)制1的細(xì)胞(如:細(xì)菌、生殖細(xì)胞、癌細(xì)胞)能無(wú)限傳代,而體細(xì)胞則不能.這兩類篩選機(jī)制背后有更深刻的原因,而細(xì)胞的癌變正是從機(jī)制2退化為機(jī)制1的過(guò)程。
