3. BigDecimal rounding question stackoverflow.com. I would like to be able to round up any number to quater of the whole number. For example: 100.33 -> 100.50 100.12 -> 100.25 100.66 -> 100.75 100.99 -> 101.00 100.70 -> 100.75 100.00 -> 100.00 100.25 -> ...
Alcoholism IS genetic: Scientists identify key DNA which makes some people more vulnerable to the addiction. 1  Scientists have discovered a DNA network causing alcohol dependence. 2  Alcoholics have a particular set of genes that may be inherited. 3  Study could lead to treatments for alcoholism and doctors screening for it.
Discovering Addiction Genes. Many genes with roles in addiction were identified with the help of animal models, especially mice. Because the reward pathwayâand many of the genes that underlie itâfunctions in much the same way in mice as it does in people, mice are leading the way in identifying addiction genes. When researchers discover a gene that plays a role in addiction in a model organism, such as mouse or fruit fly, they can then identify the counterpart gene in humans by looking for similar DNA sequences. To the right, you will find a sampling of some of the genes suspected to play a role in addiction, many of which were identified first in animals. 1  The A1 allele of the dopamine receptor gene DRD2 is more common in people addicted to alcohol or cocaine.
