End of telophase II (number per nucleus) Cell Division: Cell division is a fundamental process by which cells reproduce and multiply. It involves the replication and distribution of genetic material, followed by the division of the cell into two daughter cells, ensuring growth...
(see illustration). The series of events that prepare the cell for mitosis is known as the cell cycle. When viewed in the context of the cell cycle, the definition of mitosis is often expanded to include cytokinesis, the process by which the cell cytoplasm is partitioned during cell ...
In telophase II, what is the c-value for one of the cells that is in this stage of meiosis (assuming no problematic (non-disjunction) events occur)? Consider a diploid cell that undergoes meiosis with 44 total chromoso...
Retention of CCAN proteins in a few discrete orders in the subphyla of Pucciniomycotina and Ustilogamycotina suggests the occurrence of multiple independent loss events of most CCAN subunits (Fig.1a). The kinetochore linker CENP-CMif2was the only conserved CCAN component across basidiomycetes. Ot...
1d). As the nuclear envelope reforms at the end of mitosis, we speculated that nuclear export of GEN1 must occur at telophase, and that LMB might specifically block the transport of GEN1 to the cytoplasm at this stage of the cell cycle. This was indeed shown to be the case because, in...

1.The first stage of mitosis, during which the chromosomes condense and become visible, the nuclear membrane breaks down, and the spindle apparatus forms at opposite poles of the cell. 2.The first stage of meiosis, constituted by a series of events that include the thickening and coiling of ...
The cell cycle is the sequence of events that take place to enable DNA replication and cell division. It can be divided into two phases: interphase and mitosis. Interphase is further divided into t...
The perichromosomal layer is indicated by arrows, and the prenucleolar bodies of telophase cells are indicated by arrowheads. (E) EGFP-R19 bound with interphase prenucleolar bodies (arrowheads), which formation was induced by hypotonic treatment. (F) EGFP-19 is not a component of the nuclear ...
of nucleolar morphology with great precision (Montgomery1898). In 1934, McClintock proposed that the “nucleolus is organized in the telophase through the activity of ... the nucleolar-organizing body” (McClintock1934). Since the nucleolar-organizing body corresponds to a specific region of ...
