A pronucleus (pl.: pronuclei) denotes the nucleus found in either a sperm or egg cell during the process of fertilization. The sperm cell undergoes a transformation into a pronucleus after …

5 天之前 · The pronuclei (singular: pronucleus) are the initial male and female nuclei, containing their respective genetic material, that occur in the early zygote. These two haploid nuclei fuse …

Fertilization is not complete, however, until the two haploid nuclei (called pronuclei) have come together and combined their chromosomes into a single diploid nucleus. In fertilized …

原核融合（pronuclei fussion）是指雄性原核和雌性原核发生融合的现象。

In embryology, the nuclear material of the head of the sperm (male pronucleus) or of the oocyte (female pronucleus), after the oocyte has been penetrated by the sperm; each pronucleus …

2021年2月5日 · The mechanisms that then move the pronuclei inwards for their unification are only poorly understood in mammals. Here, we report two mechanisms that act in concert to …

The pronuclei are far from merely a passive staging area for the two parental genomes prior to assembling the zygotic genome. Both sets of chromatin undergo asynchronous DNA synthesis …

我们通常把这个时候所谓的“核”称为原核(pronuclei)——吸出来；B：已经吸了出来；C：注入与被吸出来的原核异性的另外一个原核；D：已经注入。 有一堆科学家进行了这个实验。

The unpacked DNA is enclosed in the slowly forming paternal and maternal pronuclei. During a synthesis phase the duplication of the DNA occurs in them. After the synthesis phase, which …

* These microtubules extend throughout the egg and contact the female pronucleus, and the two pronuclei migrate toward each other (Hamaguchi and Hiramoto 1980; Bestor and Schatten …
