两三个

Methylation is negative correlation with genetic transcription , and the mechanism is probably as follows : directly interfere the combination of specific transcripton and recognition site of each promoter ; mediated transcription inhibition by change the construction of chromatin; induced gene silencing by combination of methylation site and transcription inhibition. P16 gene is also called multiple tumor supresser gene , which is the best easily to methylate in the anti-oncogenes. P16 gene locates in 9p21 of mankind-chromatosome , and it's total length is 8.5kb .

甲基化与基因转录呈负相关，其机制可能是[3]：直接干扰特异的转录子和各自启动子识别位点的结合；通过改变染色质结构，介导转录抑制；甲基化DNA位点直接与转录抑制子结合，诱导基因沉默。p16基因又称为多肿瘤抑制基因( multiple tumor suppressor 1 ，MTS1) [4] ，是肺癌中最易发生甲基化的抑癌基因，该基因位于人类染色体9p21上，全长8.5kb ，由两个内含子和三个外显子组成。

He found that the interval of an octave is rooted in the ratio 2:1,that of the fifth in 32,that of the fourth in 4:3.and that of the whole tone in9:8.the phthagoreans applied these ratios to lengths of a string on an instrument called a canon,or monochord(a board with two bridges between which a string is stretched and a third bridge that divide the string in two parts);and thereby were able to determine mathematically the intonation of an entire musical system.

毕达哥拉斯将这些弦长比例应用于一种叫做卡农的乐器上，卡农也可以称之为单弦琴或者单弦音响测定器（是一个由两个码构成的木板，码子之间有一条被拉伸的琴弦，第三个码子位于琴弦两端的码子之间），因此能够用数学的方法测定整个音乐系统的音调。
