Basically, survival factors inhibit apoptosis in particular tissues. These factors bind to the cell-surface receptors thereby initiating... View Article
Most animal cells comprise the molecular machinery essential for apoptosis and hence are ready to self destruct. Whether alive or dead is based... View Article
In animal cells, the coordination of division and growth is obtained by many combinations of the generally occurring mechanisms. Division, as in... View Article
Yeast cell size is not always constant: small changes in the average size of cells in a population can occur under certain conditions. This... View Article
Yeast cells can encounter sudden large changes in the levels of nutrients in their environment— and should instantly respond with widely... View Article
Several eukaryotic cells can adjust their rate of growth responding to changes in different regulatory factors, which include the concentration... View Article
Cell growth is the phenomena wherein a cell increases its size by synthesizing the proteins, membranes, organelles and other components that make... View Article
The rate of cell division is governed by a combination of intracellular and extracellular factors. Yeast proliferation is limited primarily by... View Article
After meiosis II, haploid nuclei are packaged into cells that differentiate into specialized cell types, such as spores in yeast or gametes... View Article
DNA synthesis is a vital event that must take place after mitosis, however, must never occur after meiosis I. Robust mechanisms are present to... View Article
The mechanisms driving the completion of meiosis I is related to but distinct from those controlling the completion of mitosis. As in mitosis,... View Article
The separation of the homologs in the first meiotic division is immediately followed by entry into meiosis II. As in mitosis, the central... View Article
The pulling forces of the meiotic spindle at metaphase I are opposed only by sister-chromatid arm cohesion distal to the chiasmata. Anaphase I is... View Article
It is the ability of one crossover to suppress the formation of other crossovers in the vicinity. It could facilitate the effectiveness of... View Article
Effective homolog linkage depends on the positioning of chiasmata along the chromosomes. If homologs are linked by a single chiasma that is very... View Article
Accurate chromosome alignment in meiosis I require connections between homolog pairs. In most species, this linkage depends on the chiasmata that... View Article
