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.

Cancer is unchecked cell growth. Mutations in genes can cause cancer by accelerating cell division rates or inhibiting normal controls on the system, such as cell cycle arrest or programmed cell death. As a mass of cancerous cells grows, it can develop into a tumor.or example, many cancer cells carry two mutant copies of the gene that codes for p53, a multifunctional protein that normally senses DNA damage and acts as a transcription factor for checkpoint control genes. Gene mutations accumulate over time as a result of independent events.
