Definition of epigenetic in English: epigeneticadjective ˌɛpɪdʒəˈnɛtɪkˌɛpədʒəˈnɛdɪk 1Biology
Relating to or arising from non-genetic influences on gene expression. 外成致癌物质。 Example sentencesExamples - Hence, we investigated molecular genetic and epigenetic events in oral carcinogenesis.
- There are epigenetic influences at work (changes in inheritance by means other than changing DNA sequence,) and we're just barely starting to understand them.
- However, backcrossing is a gradual procedure that, apart from being lengthy, cannot ascertain that genetic and epigenetic changes will modify the original nuclear genotype.
- The embryo is human, since it has the genetic constitution and epigenetic primordia characteristic of human beings.
- Such variations might arise from minor genetic differences or by epigenetic influences causing induction, enhancement or inhibition of repair enzyme synthesis or activity.
- 1.1 Relating to or of the nature of epigenesis.
〔生〕渐成的
2Geology
Formed later than the surrounding or underlying rock formation. 〔地质〕后生的；外成的 Example sentencesExamples - The metamorphic rocks along the northwest margin of the Reading Prong, as well as the adjacent Paleozoic carbonates, contain epigenetic minerals deposited predominantly in open spaces.
- Ores formed at the same time as their host rocks are referred to as syngenetic; ores formed after the host rock are called epigenetic.
- Thus, the ore minerals form after the host rock and are called epigenetic.
- More recent studies suggest an epigenetic origin, indicating that sulphide-rich iron formation is a replacement type rather than a primary sedimentary facies.
- A number of different theories are postulated for the formation of the copper deposits, but all generally agree that the deposits are epigenetic and that the ore-bearing solutions were hydrothermal.
Derivativesadverb An alternate proposal suggests that centromere functionality might be epigenetically determined by a higher-order structure dictated by underlying repeats. Example sentencesExamples - In plants, numerous processes are epigenetically regulated.
- Intelligence is an emergent property of person-in-society, not an inborn capability or an epigenetically developed trait of individuals.
- On the other hand, gene redundancy triggers diploidization where duplicated genes may be eliminated, silenced, mutated to acquire new functions, or epigenetically regulated for tissue-specific expression.
- The state of gene inactivation is inherited epigenetically through multiple mitoses.
noun In the first chapter, he traces the emergence of the modern conception of the gene back to the 18th century debate between preformationists and epigeneticists. Example sentencesExamples - The epigeneticist view was clearly wrong, because something stable had to be transmitted across generations.
