What do we know about the cell that begins meiosis? What would happen if synapsis did not occur in meiosis? Can meiosis occur in somatic cells? What are the unique events that occur during meiosis? Why does synapsis occur in meiosis and not mitosis?
two rounds of mitosis with two synthesis phases are required to result in four daughter cells, while meiosis produces four daughter cells with just one synthesis phase. If resources are depleted, then organisms have problems to continue mitotic cell divisions because homologous recombinational repair ...
What are the roles of genes, alleles, chromosomes, meiosis, and mitosis in assuring that your cells have all the necessary machinery that make you the fully functioning organism that you are? What role does mitosis play...
The second possibility is that apoptosis does not take place and mitotically reactivated OLGs continue their transition from G1 to other phases of the canonical cell cycle. This should eventually lead to mitosis and a subsequent increase in the proliferation rate of OLGs, suggesting increased ...
However, although tumor cells do inappropriately proliferate, the fraction of cells in mitosis at any time within a solid tumor can be very small, likely too small to explain the amount of cell death observed with anti-mitotic drug treatment (reviewed in Mitchison57 and Komlodi-Pasztor et al....
The resulting paper [1], published in 2003 in what was then Journal of Biology (now BMC Biology), was one [1] of three [2, 3] connecting these two kinases and that helped to swell of a surge of interest in the metabolism of tumor cells that was just beginning at about that time ...
1. Why is the whitefish used to study mitosis? 2. What are the four stages of mitosis? 3. How long does it take for mitosis to complete? Why will most of the cells you view be in interphase? View CellsClick to View Whitefish Embryo ...
IV. How does a cellular environment shape rare events? The first single-cell RNA-seq datasets confirmed what many biologists had already suspected: that substantial expression heterogeneity exists between cells in a tissue, and that this heterogeneity underlies a wide range of diseases. For instance...
1. Mitosis is a process of cell division where one cell divides into two. What are TWO reasons cells need to be able to perform mitosis? 2. What is the main purpose of meiosis and what are the key events for a cell to achieve it? 3. How does the amount ...
How is EV-DNA taken up by the recipient cells in the tumor microenvironment, and what are the downstream functional responses triggered for sensing this extracellular DNA? Does the gDNA/mtDNA packaging in vesicles affect its organization and its fate in recipient cells?
