Newer estimates indicate that the average human gene contains as many as five PASs.59 A large proportion of these (81%) reside in promoter-proximal introns and are rarely used. If these intronic poly(A) signals (IpA) were employed, they would give rise to truncated proteins and so their ...
Minute amount of DNA in picograms, which was collected at different intervals is enough for amplification of SRY gene and tooth brush ca 与这项研究,我们认为, PCR是一个可贵和敏感做法,详细的污秽在结果也许导致改变,即, 4位女性显示假阳性结果。 微小数量脱氧核糖核酸在picograms,收集在不同的间隔时间...
