Which stage of mitosis is characterized by the chromosomes becoming visible as discrete structures? During which phase of mitosis do the chromatids become chromosomes? When during the cell cycle do chromosomes first become visible? What is the final phase of mitosis called in which the two nuc...
by attaching to the fibers of the cell spindle. The pairs of chromatids then separate, each strand of a pair moving to an opposite end of the cell. When a new membrane forms around each of the two groups of chromosomes, division of the nucleus is complete. The four main phases of ...
Regulation at the level of protein expression has not been addressed, and it is not known whether de novo CDK1 protein synthesis is required during mitosis. Mitosis is characterized by a switch from cap-dependent to cap-independent translation initiation. There is a general decline in protein ...
Mitosis in the protostelid Planoprotostelium aurantium Olive and Stoianovich is characterized by an open, centric spindle. The nuclear envelope breaks down prior to metaphase, begins to reform during late anaphase, and is complete by telophase. Centrioles are present at the poles throughout mitos...
The stage of mitosis that is characterized by the nuclear envelope assembling around chromosomes that are clustered at opposite spindle poles is called: a. metaphase b. anaphase c. telophase d. prophase e. prometaphase In which stage of mitosis do microtubules attach to kine...
Left panel: Prior to anaphase, the centromeres of sister chromatids are held together by cohesion proteins. Middle panel: Upon proper attachment of the spindle to kinetochore complexes, the APC/C complex targets securin for degradation. Separase is released from securin and cleaves cohesins, ...
Erynia neoaphidisUltrastructureAn account of mitosis in the aphid-pathogenic, entomophthoraceous fungus Erynia neoaphidis is presented. The mitotic apparatus is characterized by a closed, intranuclear, polarized spindle. Chromosomes are permanently attached by kinetochore microtubules (kcMTs) to the ...
the ordinary process of mitosis as it occurs in the somatic or body cells, characterized by the formation of the prescribed number of chromosomes, appropriate for the species (in humans the number is 46). Farlex Partner Medical Dictionary © Farlex 2012Want...
Angiosperm reproduction is characterized by alternate diploid sporophytic and haploid gametophytic generations. Gametogenesis shares similarities with that of animals except for the formation of the gametophyte, whereby haploid cells undergo several rounds of postmeiotic mitosis to form gametes and the accesso...
Prometaphase is the second stage of mitosis (it has also been referred to as late prophase). This stage is characterized by increased condensation of chromosomes as well as the breakdown of the nuclear envelope (nuclear membrane). The nuclear envelope, which consists of an inner and outer ...
