Segregating sister chromatids during the first meiotic division represents an atypical process when compared to regular meiosis, but the real challenge is to orderly distribute homologous non ...

Consequently, females are born with a finite number of oocytes arrested in the first meiotic prophase ... or replicating their DNA. Meiosis II resembles a mitotic division, except that the ...

Both general cell-cycle regulators and meiosis-specific proteins bring about this modified cell division. Although pre-meiotic S phase uses the same replicative machinery as pre-mitotic S phase ...

Meiosis is a specialized form of cell division that produces reproductive ... Metaphase I: The meiotic spindle, a network of protein filaments, emerges from two structures called the centrioles ...

In meiosis, prophase, metaphase, anaphase and telophase occur twice. The first round of division is special, but the second round is more like mitosis. In mitosis, prophase, metaphase, anaphase and ...

Scientists have characterized a mechanism that allows for asymmetrical cell division during meiosis in oocytes ... chromosome movement in mammalian meiotic oocytes," said Hongbin Li, Ph.D ...

Topo II is present in many different cells including cells that are undergoing the specialized cell division of meiosis. Much less is known about the role of Topo II in the meiotic cell cycle. We are ...

Usually cell division is of three types: (i) Amitosis (ii) Mitosis (iii) Meiosis Amitosis: This cell division takes place in less developed cell of unicellular organism and firstly nucleus of the ...

Cyclin B3, on the other hand, plays an important role in meiosis, another type of cell division. It is responsible for ensuring that meiotic division takes place correctly and that a healthy egg ...

unveils a phosphoproteomic census covering the entire meiotic cell division program in budding yeast. Sexually reproducing organisms rely on a specialized cell division program—meiosis—to form ...

His research group focuses on cell division, centromere function in the germline ... Centromere drive depends on a combination of asymmetries in female meiosis. Meiotic drive of Rb fusions illustrates ...

Certain alleles, called meiotic drivers ... when cells from the germline undergo two rounds of specialized cell division—meiosis I and meiosis II—to form gametes (egg and sperm cells).
