受精卵

These changes and mutations only have an effect at the point where a new zygote is created.

这些转变只在受精卵产生时才起作用。

Embryonic development is one of the most important basic questions in biology. All of the multicellular organisms are developed from a single cell, zygote.

胚胎发育是生物学研究中最重要的基本问题之一，所有的多细胞生物都是由一个单细胞——受精卵发育而来。

So what scientists are going to do is that they try to clone a person, attempting to get stem cells from their "zygote". It is this action that shocks the world.

那么，科学家是做的是，他们试图克隆人，企图从"受精卵"中获得干细胞，正是这一行动引起了世界的轩然大波。

In unitary populations, each zygote gives rise to a single individual.

在单体生物种群中，每一受精卵发育成一单个个体。

Objective: To research the expression of phosphodiesterase 3A (PDE3A) in zygote of mouse during the first mitosis.

目的：研究磷酸二酯酶3A(PDE3A)在小鼠受精卵第1次有丝分裂中的表达。

The sperm treated with trypsin, plasmin, pepsin and succinic acid sodium respectively, only trypsin can dissociate the eupyrene sperm bundles and improve the motility of apyrene sperm synchronously, and olso only the trypsin-treated sperm have the ability of fertilization.

用胰蛋白酶、血纤维蛋白溶酶、胃蛋白酶及琥珀酸钠处理精液，仅胰蛋白酶能够在很好的溶解有核精子束的同时提高无核精子的运动性，也只有胰蛋白酶处理的精液人工授精能够得到受精卵。

The effect of polyhexamethylene biguanide and Sodium dichloroisocyanurate on zygote and nauplii of Fenneropenaeus chinensis was studied.
