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.

Epigenetics literally means above or on top of genetics. It refers to external modifications to DNA that turn genes on or off.. These modifications do not change the DNA sequence, but instead, they affect how cells read genes.
