在1876到1878年间，奥斯卡·赫特维希的数份有关海胆卵细胞受精作用的研究显示，PCR检测试剂盒的细胞合会进到卵子的内部，并与卵子细胞核融合。首度阐释了生物个体由单一有核细胞发育而成的可能性。这与恩斯特·海克尔的理论不同，海克尔认为物种会在胚胎发育时期重演其种系发生历程，其中包括从原始且缺乏结构的黏液状“无核裂卵”（Monerula），一直到有核细胞产生之间的过程。因此精细胞核在受精作用中的必要性受到了漫长的争论。赫特维希后来又在其他动物的细胞，包括两栖类与软体动物中确认了他的观察结果。而爱德华·施*布格也从植物得到相同结论。这些结果显示了细胞核在遗传上的重要性。1873年，奥古斯特·魏斯曼提出了一项观点，认为母系与父系PCR检测试剂盒细胞在遗传上具有相等的影响力。到了20世纪初，有丝分裂得到了观察，而孟德尔定律也重新见世，这时候细胞核在携带遗传讯息上的重要性已逐渐明朗核酸检测试剂盒。
6细胞核遗传核酸检测试剂盒
核酸检测试剂盒细胞核遗传是指由细胞核内遗传物质控制的遗传现象；细胞质遗传是指由细胞质内的遗传物质控制的遗传现象。生物的遗传是细胞质遗传和细胞核遗传共同作用的结果。以下是它们的不同点：
一、细胞核遗传中，除伴性遗传外，其亲本不论是正交还是反交，子代的表现型均为显性性状，细胞质遗传，亲本的正交和反交结果不同，子代只表现出母体性状。
二、细胞核遗传，符合遗传三大规律（孟德尔的分离规律，孟德尔的自由组合规律，连锁与互换规律），杂交后代有一定的分离比。细胞质遗传，其基因不像核内染色体上的基因能进行有规律地分离和组合，杂交后代不出现性状分离，也不存在自由组合的连锁互换现象。
三、细胞核遗传，核基因可在染色体上进行定位，细胞质遗传中，质基因不能定位。
四、细胞质和细胞核的遗传物质都是DNA分子，但是其分布的位置不同。细胞核遗传的遗传物质在细胞核中的染色体上；细胞质中的遗传物质在细胞质中的线粒体和叶绿体中。
五、细胞质和细胞核的遗传都是通过配子，但是细胞核遗传雌雄配子的核遗传物质相等，而细胞质遗传物质主要存在于卵细胞中；
六、细胞核和细胞质的性状表达都是通过体细胞进行的。核遗传物质的载体（染色体）有均分机制，遵循三大遗传定律；细胞质遗传物质（具有DNA的细胞器如线粒体、叶绿体等）没有均分机制，是随机分配的。
七、细胞核遗传时，正反交相同，即子一代均表现显性亲本的性状；细胞质遗传时，正反交不同，子一代性状均与母本相同，即母系遗传。

Between 1876 and 1878, Oskar Hewittich's several studies on the fertilization of sea urchin eggs showed that the cell line of the PCR test kit went inside the egg and was fused to the egg nucleus. For the first time explain the possibility of biological individuals from the development of a single nucleated cell. Unlike Ernst & Hacker's theory, Hycker argued that species will reproduce their phylogeny during embryonic development, including from primitive and unstructured mucoid "Monerula" Until the process of nucleated cells. Therefore, the need for sperm nucleation in fertilization is subject to long debate. Hewittich later confirmed his observations on other animal cells, including amphibians and molluscs. And Edward Strasbourg got the same conclusion from plants. These results show the genetic importance of the nucleus. In August 1873, August Weisman came up with the idea that the maternal and paternal PCR test kit cells were genetically equally influential. By the early twentieth century, mitosis was observed, and Mendel's law was also seen again. At this time, the importance of the nucleus in carrying genetic information has gradually become clear nucleic acid detection kit.
6 Nucleic Acid Nucleic Acid Assay Kit
Nucleic Acid Detection Kit Nucleus inheritance refers to the genetic phenomenon controlled by the genetic material in the nucleus. Cytoplasmic inheritance refers to the genetic phenomenon controlled by the genetic material in the cytoplasm. Biological inheritance is the result of both the cytoplasmic and the nuclear genetic interactions. The following is their difference:
First, the nucleus genetic, in addition to sexually transmitted, the parents whether orthogonal or anti-cross, the progeny phenotype are dominant traits, cytoplasm genetic, the parents of the results of orthogonal and anti-cross, the offspring only Maternal traits.
Second, the nuclear genetics, in line with the three major laws of inheritance (Mendel's law of separation, Mendel's law of free association, linkage and exchange laws), hybrid offspring have a certain separation ratio. Cytoplasmic inheritance, the gene is not like nuclear chromosome genes can be a regular separation and combination of hybrid offspring does not appear trait separation, there is no free combination of the phenomenon of interchanging.
Third, nuclear genetics, nuclear genes can be located on chromosomes, cytoplasmic genetic, qualitative genes can not be located.
Fourth, the cytoplasm and nucleus of genetic material are DNA molecules, but its distribution in different locations. The genetic material of the nucleus is on the chromosomes in the nucleus; the genetic material in the cytoplasm is in the mitochondria and the chloroplast in the cytoplasm.
Fifth, cytoplasm and nucleus are inherited by gametes, but the nuclear genetic male and female gametes nuclear genetic material equal, and cytoplasmic genetic material mainly in the egg cells;
Six, nuclear and cytoplasmic traits are expressed through somatic cells. The carriers (chromosomes) of the nuclear genetic material have an equalization mechanism and follow the three major genetic laws. The cytoplasmic genetic material (DNA-containing organelles such as mitochondria, chloroplasts, etc.) does not have an equalization mechanism and is randomly assigned.
Seven, nucleus inheritance, reciprocal reciprocation is the same, that is, the first generation of subgenus showed dominant parental traits; cytoplasmic heredity, reciprocal reciprocal cross, the first generation of traits are the same as the female parent, that maternal inheritance.
