In a shift away from GMOS, aka genetically modified organisms, important research is continuing in gene editing, sometimes ...

A second example of how chemical environments affect gene expression is the case of supplemental oxygen administration causing blindness in premature infants (Silverman, 2004). In the 1940s ...

In addition, gene expression changes can lead to changes in an entire organism, such as molting in insects. In Drosophila, for example, the molting process is regulated by levels of a hormone ...

ETH researchers have developed a new gene switch that can be activated using a commercially available nitroglycerine patch applied to the skin.

Finally, the chances that their child will have two copies of the gene, and therefore sickle cell anemia, is also 25 percent. This situation is a stark example of genetic compromise, or an ...

The founder effect is an extreme example of "genetic drift." Genes occurring at a certain frequency in the larger population will occur at a different frequency -- more or less often -- in a ...

This genetic diversity stems from mutations. Often, these mutations are not helpful. But at times, they can enable populations to adapt to change. For example, golden kelp (Ecklonia radiata ...

Half of the possible offspring have the same allele combination; AA homozygous dominant and the other half have the Aa heterozygous combination. Probability close probabilityThe extent to which ...

Christie is a seasoned science journalist and cell and molecular biology PhD; her debut book Venomous: How Earth’s Deadliest Creatures Mastered Biochemistry, received widespread acclaim. She was a ...
