Understanding the steps of meiosis is essential to learning how errors occur. Researchers' initial understanding of meiosis was based upon careful observations of chromosome behavior using light ...

Meiosis is the generation of germ cells (eggs and sperm). In meiosis, DNA replication is followed by two division cycles: meiosis I, which segregates homologous chromosomes and meiosis II ...

In the United States, more than 11% of men under the age of 49 are infertile. While the causes are varied and range from ...

A genetic mutation in mice affects cells required for sexual reproduction and holds clues about male infertility that could pave the way for new treatments and male contraceptives, a Rutgers ...

They are formed in a woman's body before birth and have to be on standby for decades to possibly be fertilized one day. But as they age, they accumulate more and more DNA damage. Until now, it has ...

Here is a look at the NEET UG 2025 syllabus and answers to frequently asked questions regarding the Biology subject.

Munich news, health insurance, technology, jobs and other topics for expatriates. The Eye Newspapers covers daily news and offers services for foreigners.

In the United States, more than 11% of men under the age of 49 are infertile. While the causes are varied and range from infections to hormonal imbalances, deformities during meiosis - a specialized ...

This sets up a new structure that cements the cell's future fate as a sperm cell. The companion paper shows that well before the germ cells enter meiosis, CTCF and other proteins bookmark thousands of ...

Single-cell multiomic analyses reveal known and new genes and pathways involved in the development of germ cells and provide a discovery platform for the scientific community.

Kelainan langka trisomi 13 atau Sindrom Patau bisa dialami sejak bayi di dalam kandungan. Lantas, bisakah kondisi ini dicegah?

这项研究首次系统地揭示了细胞间桥在减数分裂中的具体作用机制，研究者指出，细胞间桥不仅参与了生殖细胞的DNA复制和损伤修复，还对转座子（一种可以移动的基因元件）的沉默起到了关键作用。在正常情况下，转座子的活性被严格抑制，以防止它们对基因组造成破坏，然而当细胞间桥功能受损时，转座子的活性会被释放，这就进一步加剧了生殖细胞的损伤。这一发现不仅为理解男性不育的遗传基础提供了新的视角，也为开发新的治疗方法和 ...
