epigenetics

(ĕp′ĭ-jə-nĕt′ĭks)
n. (used with a sing. verb)
The study of heritable changes in gene expression that are caused by factors such as DNA methylation rather than by a change in the sequence of base pairs in DNA itself.

epigenetics

(ĕp″ĭ-jĕ-nĕt′ĭks)
Changes in the way genes are expressed that occur without changes in the sequence of nucleic acids. In mammals the most common form of epigenetic change results from methylation (the addition of methyl [-CH3] moieties) to the promoter regions of genes. Although epigenetic changes do not alter the sequence of nucleotides, they are inheritable.

Numerous examples of the dominance of hypogene speleogenesis occur throughout the greater Delaware Basin region, though the specific composition of the fluids and host rocks differ; however, epigene karst is also common in the Castile Formation, and other evaporite strata in the region, because of the high solubility of gypsum (Stafford et al.
Epigene speleogenesis occurs in unconfined settings and it is directly associated with meteoric precipitation (Palmer 1991).
The spiritual epigene does not completely change a person and his offspring forever, though.
This positive action can form an epigene that can overcome bad genes.
Second, we investigated whether associations between N[O.sub.2] exposure and methylation levels in the top 25 CpGs (corresponding to p < 2.59 x [10.sup.-5]) in the cord blood analyses persisted in older children, employing a single CpG look-up approach in available samples of 4-year-olds (pooled MeDALL sample), as well as in 8-year-olds (meta-analyzed pooled MeDALL sample and the BAMSE EpiGene).
Second, epigenes can be passed on in the Off position, to successive generations.
Epigenes: Oh god I've had it; I'm already close to the door dragged along.

a.-- La introduccion de las concepciones cuantitativas y mecanicas en biologia que se observan, primero en el gran descubrimiento de la circulacion de sangre de Harvey (1628), los esfuerzos cartesianos por explicar este fenomeno en terminos exclusivamente mecanicos (1648) hasta las fuertes y extendidas discusiones sobre el preformismo y la epigenes. Fue en esta disputa en la que se probo la fuerza de las explicaciones mecanicas y de su opuesta la explicacion vitalista; tentacion esta ultima a la que vemos moverse los pensadores cuando surgen nuevos fenomenos que no son explicables con las teorias mecanicas vigentes.

1098, where Epigenes uses the same exclamation to express the pain caused by his unsatisfied erection--and the frustration he feels at his inability to have sex with his young girlfriend, exacerbated by the demands of the old hags whom he is legally bound to bed first.
