A large population of cells is treated with a fluorescent DNA dye and then injected into an instrument called a flow cytometer, which can rapidly... View Article
It is a technique used to enumerate and analyze a sample of cells by incubating them with one or more fluorescently labelled antibodies and/or... View Article
A more specific approach to disrupting gene expression in mammalian cells is RNA interference (RNAi), which triggers the destruction of a... View Article
The major weakness of mammalian cells as an experimental system is the lack of rapid and specific methods for blocking gene and protein function... View Article
Transformed cell lines have accumulated widespread genetic damage that not only results in immortalization but also disrupts the controls that... View Article
When grown for long periods in culture, cells in a population can accumulate spontaneous mutations that prevent senescence, resulting in... View Article
Senescence in some cells, particularly human cells, is due to changes in the structure of the telomere, a complex DNA–protein structure... View Article
Cell senescence results from at least two general mechanisms. One of which is - many cell types (particularly rodent cells) are thought to... View Article
A mammalian cell-cycle analysis is best performed with cells that have been taken directly from the animal and grown in plastic dishes containing... View Article

After fertilization, the fusion of sperm and egg nuclei results in a zygote nucleus that undergoes a series of rapid and synchronous divisions... View Article
Not all the components of proteins are duplicated by the continuous synthesis in the process of the cell cycle. Centrosomes of animal cells are... View Article
They reproduce by continuous division and growth of the already existing organelles. Lysosomes and mitochondria, the smaller organelles are seen... View Article
It is considered so as it is in this phase that most of the cells get committed either to continued division or exit the cell cycle. When there... View Article
These are movements seen in plants occurring while responding to the environmental stimuli, however, in contrast to tropic movements, the path of... View Article
Carbon skeletons of non-essential amino acids are generated from intermediates of the TCA cycle and glycolysis exception being the synthesis of... View Article
Tropism is a direction movement occurring in response to a direction based stimulus. Since plants cannot migrate and relocate, it starts growing... View Article
