Abstract: Although there are many methods to estimate the early postmortal interval,more attention has been paid to the research on measuring the amount of DNA in cells. This paper introduce several different measuring ways,law of variation and application situation of DNA in cells. In addition,the result evaluation of measuring methods and application prospect is given.
