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.

Epigenetics is an emerging science focused on how and when particular genes are turned on or off. Diet and exposure to chemicals in the environment, among other factors, can alter a cell's DNA in ways that affect the activity of genes. That can make people more or less susceptible to developing a disease.n other diseases, a genetic variant may occur. A single gene can have many variants. Sometimes, this difference in a gene can cause a disease directly. More often, a variant plays a role in increasing or decreasing a person's risk of developing a disease or condition.
