The article discusses highlights of the 48th Annual Meeting of the American Society for Cell Biology (ASCB) held in San Francisco, California from December 13 to 17, 2008. Arshad Desai was given the Early Career Life Scientist Award at the event. Ekaterina Grishchuk, lead author on the ...
Why do somatic cells divide by mitosis? Why must DNA be packaged into chromosomes before mitosis or meiosis can occur? Why does meiosis produce cells with half the chromosomes? Why do cells have 4 homologous chromosomes during prophase of mitosis instead of 2?
The finding that transition from mitosis to meiosis may occur in cultured plant cells, and therefore possibly an alternative pathway of the mitotic process under stressing conditions, may offer a possible solution for the totipotency enigma. These data and the unexpected finding that plants ...
Cells divide and reproduce in two ways, mitosis and meiosis.Mitosis results in two identical daughter cells, whereas meiosis results in four sex cells. Below we highlight the keys differences and similarities between the two types of cell division. ...
and the processes of mitosis and meiosis in rice cell were observed under microscope and recorded by photograph.[Result] The interphase and all the four phases of mitosis including prophase,metaphase,anaphase and telophase were well observed.At metaphase,the chromosomes condensed to the minimum,thus ...
The observed asymmetric interphase chromatin localization could be mediated via direct or indirect microtubule—Cid attachments. In the case of a direct attachment, we would expect to see microtubules penetrating the nuclear envelope prior to mitosis entry. To address this question, we stained wild typ...
Cool, I just learned about mitosis and meiosis this week in biology class. We learned that they go through a lot of the same steps except meiosis repeats the steps twice. For anyone learning about the processes, just remember IPMAT for the phases - interphase, prophase, metaphase, anaphase,...

Since 108600 induces a conformational change in the CK2α subunit by potentially interfering with its ability to bind to the β-subunit, we examined the effects 108600 on CK2-holoenzyme-mediated tubulin dynamics in vitro and assessed its effects on mitosis. We adapted and employed a published ...
