We have 5 results for Endopolyploidy.
1 Citation Gene amplification involves the production of multiple copies of a gene through repeated copying of the gene. Amplification is distinct from duplication , which is precise genome doubling preparatory to cell division , and from endoreduplication , which leads to endopolyploidy . When many copies of the amplified region are produced, they can form their own small pseudo-chromosomes called 'double-minute chromosomes' . Gene amplification results from dysfunction in malignant cell lin, technorati.com

1 Citation Bar?iene J, Tapia G, Barsyte D. 1996. Chromosomes of molluscs inhabiting some mountain springs of eastern Spain. Journal of Molluscan Studies 62: 539-543.These authors report karyotypes for four species of molluscs (three gastropods and one bivalve) collected from small, high-altitude freshwater habitats in Spain. These habitats are quite diverse, with some very small springs occupying only 3-4 m^2 of surface area. Previous studies had associated small and isolated populations with polyploidy an, technorati.com

1 Citation Erenpreisa J, Ivanov A, Cragg M, Selivanova G, Illidge T. 2002. Nuclear envelope-limited chromatin sheets are part of mitotic death. Histochemistry & Cell Biology 117: 243-255. These authors investigated the structure and formation of nuclear envelope-limited chromatin sheets (ELCS) in two lines of mutant human cells commonly used in cancer studies. ELCS are membranous structures of unknown function; they are flat folds of inner nuclear envelope that project outwards from the nucleus, som, technorati.com

1 Citation Martin GG, Oakes CT, Tousignant HR, Crabtree H, Yamakawa R. 2007. Structure and function of haemocytes in two marine gastropods, Megathura crenulata and Aplysia californica . Journal of Molluscan Studies 73: 355-365. These authors characterised the blood cells of two species of gastropods chosen for their importance to other areas of research. Other studies have reported either one or two types of cells in mollusc blood, either with or without granules visible as electron-dense patches in, technorati.com
