遗传作用

Genetic markers, especially the protein and molecular markers developed in recent years, are playing more and more important role in elucidating the mechanism of sex determination.

遗传标记，尤其是近年来快速发展起来的蛋白质、分子标记等技术，在揭示植物性别分化机理的研究中起着越来越重要的作用。

Background— Protein kinase A signaling has long been known to play an important role in cardiac function. Dysregulation of the protein kinase A system, caused by mutation of the protein kinase A regulatory subunit gene PRKAR1A, causes the inherited tumor syndrome Carney complex, which includes cardiac myxomas as one of its cardinal features. Mouse models of this genetic defect have been unsatisfactory because homozygote null animals die early in development and heterozygotes do not exhibit a cardiac phenotype.

背景——蛋白激酶A信号传导在心功能中发挥了重要作用早已为人们所知蛋白激酶A调节亚基因PRKAR1A的变化引起蛋白激酶A系统失调，导致了遗传性卡尼复合肿瘤综合症，其中包括的心脏粘液瘤作为它的一个主要特征此种遗传缺陷的小鼠模式仍然不能令人满意，因其纯合体空白动物在发展中早期死亡，而杂合体不能显示心脏表型

The reason is that the c2 distance measurement in correspondent analysis usually overrates the effect of the genes with low frequencies.

蹄型效应经常会歪曲潜在遗传结构的真实形态，其产生主要是因为对应分析中的c2距离不相似测度高估了稀有基因的作用。

DNA is a molecule that stores coded information. Another important nucleic acid—RNA—works in conjunction with DNA to bring about protein synthesis in cells.

DNA主要存在于细胞核内的染色质中，线粒体和叶绿体中也有，是遗传信息的携带者；RNA在细胞核内产生，然后进入细胞质中，在蛋白质合成中起重要作用。

The contribution and value of studies on animal individual differences to personality psychology were discussed mainly in aspects of personality constructs, influence of genetics and environment, association of personality with cognition and health, as well as personality-environment match.

文章从人格结构的探讨，遗传和环境的作用，理解人格与认知、健康的关系，以及个体与环境的匹配等方面讨论和分析了动物个体差异的研究对人格心理学的可能贡献。

That the transition from ape to man is to make the existence of phase variation, genetic and natural selection to be the basic factors play a role is one of the two-legged walking means perfect stage.

可以认为从猿到人的过渡阶段的存在是使变异、遗传及自然选择得以起作用的基本因素之一，是两足行走方式完善化的阶段。

As a powerful technique, the isozyme analysis plays an important role in study of genetic evolution and differentiation of biological species.

同功酶分析作为一种有效的研究手段在研究物种的遗传进化中显示了极为重要的作用。

Positive effects of SCA and dominance for tuber yield were significant with CH72.03×11379-03, and 08675-21×10875-04 showed significant negative effect of dominance for chipping color.

极显著的加性效应和较低的狭义遗传率(42.5％)说明基因累加作用对干物质含量的改良极为重要，该性状受微效多基因控制。

Some stimulators, including viruses, tumor cells and hot shock, could promote the expression of NKG2 receptors and their ligands via activating certain transcription factors which are capable of up-regulating NKG2 promoters' activity. Meanwhile, epigenetic mechanisms including DNA methylation and histone posttranslational modifications are also critical to expression of NKG2 receptors and their ligands and may control the clonally distribution of some NK cell receptors.

病毒、肿瘤和热休克等刺激可以通过激活相应的转录调节因子，提高启动子活性而上调NKG2家族受体及其配体的表达，而启动子区DNA的甲基化状态、组蛋白的乙酰化和甲基化等表观遗传调控，在NK细胞受体及其配体的表达方面亦起重要作用，并决定NK细胞受体的克隆性分布。

As the bridge between nucleic acid and protein, codons have many important functions during the transference of genetic information.

密码子作为核酸与蛋白质这两大生物功能分子联系的纽带，在遗传信息的传递过程中具有重要的作用。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。

The cost of moving grain food products was unchanged from May, but year over year are up 8%.

粮食产品的运输费用与5月份相比没有变化，但却比去年同期高8％。
