Cell Growth W.T.Godbey, inAn Introduction to Biotechnology, 2014 5.1.1Phases of Mitosis Let us now consider mitosis in a little more detail. Looking at the cell cycle solely in terms of mitosis, there are five stages:interphase,prophase, metaphase,anaphase, andtelophase. Prophase, metaphase, ...
Chromosomes carry the genetic material in the cell because they are made of DNA and proteins. Chromosomes are crucial to ensure that each cell gets the same copy of DNA. The cell is able to produce two daughter cells by a series of phases known as prophase, metaphase, anaphase, telophase,...
The major phases of the cell cycle are called interphase and M phase (mitotic phase). What happens in cell division? During cell division, a cell grows, copies its DNA, and then separates the DNA copies so that each new cell can have one copy of the DNA. The cell then splits into ...
interkinesis, the stage in the life cycle of a cell between two successive mitotic divisions. A distinction is usually made between the heterosynthetic interphase, when the cell grows, is differentiated, and performs its natural functions, and the autosynthetic interphase, during which the cell pre...

As the pioneer among molecular cytogenetics techniques, fluorescence in situ hybridization (FISH) allows identification of specific sequences in a structurally preserved cell, in or . This technique, based on the complementary double-stranded nature of DNA, hybridizes labeled specific DNA (probe). Th...
An ultrastructural and radio autographic study of the effect of ethidium bromide on the interphase nucleus of meristematic plant cellsIn the present work the effects of an intermediate dose (20 渭g/ml) of ethidium bromide on nuclear ... A Lord,JG Lafontaine - 《Journal of Cell Science》 被...
This result was ascribed to a possible trancrystallization phenomenon of semi-crystalline PHO in contact with cellulose whisker surface, which prevents any contact between amorphous PHO chains and filler surface. 展开 关键词: Cellulose whiskers bacterial polyester poly(hydroxyoctanoate) interphase dynamic ...
