Answering the question, “Why do cells divide?” pretty much also answers the question, “Why is mitosis important?” The process of mitotic cell division in eukaryotic cells is important for two main reasons: because cell division creates new cells that keep eukaryotic organisms thriving, and be...
Applying our Knowledge of Cell Division Cells usually have a specific function Cells usually have a specific function Stem Cells are unspecialized cells that can develop into specialized cells under the right conditions Stem Cells are unspecialized cells that can develop into specialized cells under the...
Polyploid cells are often assumed not to be able to divide. However, Wigglesworth (1967d) showed that Rhodnius fat body cells begin larval life as tetraploids and replicate with a constant ploidy at each molt except after starvation when ploidy increases by nuclear fusion. Lepidopteran fat body ...
Replication of damaged DNA creates stranded mutations, and sister cells from the subsequent division inherit either only one type of strand (upper) or one of each strand (middle) or can undergo SCE and switch from a mixed to a phased segment (lower). b, Representative examples for each ...
We propose that a cell's life is divided into two fundamentally different parts. Some time after mitosis all cells enter a state (A) in which their activity is not directed towards replication. A cell may remain in the A-state for any lenght of time, throughout which its probability of ...
Mitosis forms somatic cells, which are also referred to as the cells of the body (having a 2n or diploid number of chromosomes). This is the type of cell division all of the cells in the body do except for those responsible for “sex cell” production. There are 4 main phases in ...
Meiosis in humans occurs in specialized cells of the testes in men and the ovaries in women. Whereas mitosis creates cells identical to the original to replace dead cells or contribute to the growth of the whole organism, meiosis generates cells called gametes designed to fuse with gametes from...
they have more differences than similarities. Most of these differences relate back to the fact that, although both are needed for cell replication,mitosis and meiosis have different purposes:mitosis replaces body cells with identical copies, while meiosis creates genetically different sex cells that ...
cells showing relatively higher expression, GFP-KIAA1377 was also observed to extensively overlap with microtubule network in interphase cells and the spindle in mitotic cells (Figure3C&D). Most interestingly, GFP-KIAA1377 co-localizes with centrin 2 at centrosomes throughout the cell cycle except ...
