英语释义

1. the study of heritable changes in gene function that do not involve changes in DNA sequence

2. the study of heritable changes in gene function that do not involve changes in DNA sequence
At its most basic, epigenetics is the study of changes in gene activity that do not involve alterations to the genetic code but still get passed down to at least one successive generation.
— John Cloud, Time, 18 Jan. 2010 Epigenetics is the study of the chemical groups that stick to DNA and act as switches to turn genes on and off.
— New Scientist, 7 July 2006

片语

Cancer EpigeneticsCancer epigenetics is the study of epigenetic modifications to the genome of cancer cells that do not involve a change in the nucleotide sequence. Epigenetic alterations are as important as genetic mutations in a cell’s transformation to cancer.

英汉例句

• epigenetics is a type of gene regulation that can be passed from a cell to its daughters. the most common mechanism is methylation.

  外因遗传是一种可以传给下一代细胞的基因调控过程，最常见的方式是通过甲基化作用来完成，该作用可以让甲基（由一个碳原子和三个氢原子组成）附着于腺嘌呤或胞嘧啶上。

• as momentous as epigenetics sounds, the chemistry of at least one of its mechanisms is fairly simple.

  实验胚胎学听起来博大精深，但它的化学机制相当简单。

• with epigenetics you look at how the genome responds to the environment. how things like toxins and diet and other things turn on the switches that regulate how certain genes are expressed.

  通过实验胚胎学你可以看到基因如何对环境作出反应，有毒物质或者饮食以及其他因素如何影响调控特定基因表达的机制。

• the definition of epigenetics is somewhat variable, with some scientists limiting the term to refer to specific molecular mechanisms that alter gene expression.

  「表观遗传的定义」有多个不同版本，某些科学家将其囿于能改变基因表达的那些特殊细胞结构中。

• at its most basic, epigenetics is the study of changes in gene activity that do not involve alterations to the genetic code but still get passed down to at least one successive generation.

  该学科主要研究基因变化，在不改变遗传密码的前提下，新特性如何成功潜入下一代。

• hoping to understand what’s happening in those clouds, epigenetics researchers have focused on biochemical switches that turn genes on and off.

  为了了解那些基因云发生的情况，遗传学研究者们必须找到开启和关闭基因的生物学开关。

• in other words, you can change your epigenetics even when you make a dumb decision at 10 years old.

  换句话说，你10岁做出一个愚蠢的决定，都有可能改变外基因。

• with epigenetics you look at how the genome responds to the enviornment. how things like toxins and diet and other things turn on the switches that regulate how certain genes are expressed.

  通过实验胚胎学你可以看到基因如何对环境作出反应，有毒物质或者饮食以及其他因素如何影响调控特定基因表达的机制。

• how can we harness the power of epigenetics for good?

  如何利用外基因善呢？

• possibly, but it「s important to remember that epigenetics isn」t evolution.

  或许会吧。我们要牢记外基因不是进化。

• here, we review the role of epigenetics in aging and longevity with a focus on dna methylation.

  这里，我们回顾了表观遗传学在衰老和长寿中的作用，集中在dna甲基化。

• whether epigenetics is important for other, more complex, behaviour remains to be seen.

  表现遗传性对其他更复杂的行为是否也很重要还不得而知。

• the concept of epigenetics offers an explanation for this result.

  表观遗传学的概念对这一结果给出了解释。

• he calls epigenetics 「perhaps the most important discovery in the science of heredity since the gene.」

  他称外基因「或许是遗传学自发现基因后，另一项最重要的发现。」

• epigenetics is a type of gene regulation that can be passed from a cell to its daughters.
