- 生殖生物学 生殖生物学
- 遗传学 是一个遗传学.
- 在体外受精中进行体外受精.
背景情况:
- 矩阵金属蛋白酶 (MMPs) 和金属蛋白酶的组织抑制剂 (TIMPs) 调节细胞外矩阵重塑,这对于植入期间的热囊细胞入侵至关重要.

01:05Single Nucleotide Polymorphisms-SNPs
13.8K
A single nucleotide polymorphism or SNP is a single nucleotide variation at a specific genomic position in a large population. It is the most prevalent type of sequence variation found in the human genome. Point mutations that occur in more than 1% of the population qualify as SNPs. These are present once every 1000 nucleotides on an average in the human genome. Replacement of a purine with another purine (A/G) or a pyrimidine with another pyrimidine (C/T) is known as a transition. In contrast,...

02:07Oogenesis
63.3K
In human women, oogenesis produces one mature egg cell or ovum for every precursor cell that enters meiosis. This process differs in two unique ways from the equivalent procedure of spermatogenesis in males. First, meiotic divisions during oogenesis are asymmetric, meaning that a large oocyte (containing most of the cytoplasm) and minor polar body are produced as a result of meiosis I, and again following meiosis II. Since only oocytes will go on to form embryos if fertilized, this unequal...
