To generate random floating-point numbers whose lower bound is 0 but upper bound is greater than 1 (or, in the case of negative numbers, whose lower bound is less than -1 and upper bound is 0), multiply the random number by the non-zero bound.
Epigenetic Changes Can Cause Cancer. A transgene designed to attract methylation to the promoter of a tumor-suppressor gene leads to tumorigenesis in a mouse model.By Ashley P. Taylor | July 25, 2014. Changes in gene methylation alone can trigger cancer, according to a mouse study published today (July 25) in the Journal of Clinical Investigation. transgene designed to attract methylation to the promoter of a tumor-suppressor gene leads to tumorigenesis in a mouse model.

Epigenetics is the study of changes in gene activity which are not caused by changes in the DNA sequence. It is the study of gene expression, the way genes bring about their phenotypic effects. These changes in gene activity may stay for the remainder of the cell's life and may also last for many generations of cells, through cell divisions.
