Not exact matches

By using pairs of sisters who spent differing amounts of time living with their fathers, the study was able to control for inherited genes and environmental conditions, such as socioeconomic status or religious background, to isolate the effects of fathering quality on daughters.

The pair of studies bring renewed focus to the epigenetics of T cells — the multilayered system of molecular switches, accelerators, and throttles that controls the activity of genes.

But genes in other regions are so close together they overlap: the cluster of 75 genes which determines tissue type and plays a part in controlling our immune responses is packed into only 4 million base pairs.

Stem cell researchers from UCLA used a high resolution technique to examine the genome, or total DNA content, of a pair of human embryonic stem cell lines and found that while both lines could form neurons, the lines had differences in the numbers of certain genes that could control such things as individual traits and disease susceptibility.

Starting in 1958, just five years after the discovery of DNA's double - helix structure, researchers suspected that a specific gene controls the orderly pairing of wheat chromosomes during reproduction.

Moreover, because trans - Tango works by instigating the expression of genes in connected pairs of neurons, it also has the potential to enable scientists to control circuit functions, says senior and corresponding author Gilad Barnea, PhD, an associate professor of neuroscience who began looking for a precise, reliable, and general way to visualize neural connections two decades ago.

A joint study by Northwestern University's Kellogg School of Management and the school's Interdepartmental Neuroscience program found that a pair of genes that regulate dopamine and serotonin in men control their risk - taking behaviour.

There are seven pairs of genes that have been identified so far that control coat color.

But most of the genetic diseases pet owners and veterinarians see only occur when both of the pair of genes that control a particular process are defective (a recessive trait).

If one of those gene pairs is defective, the lysosomes can not digest the particular substance under that enzyme's control and that substance can build up within the cell — eventually killing it.

If scientific observation shows that a genetic condition follows an autosomal recessive inheritance pattern, this determination implies that the manifestation of the condition is controlled by the presence of one recessive gene pair.
