Cell cycle parameters of maize ( Zea maysL cv Black Mexican Sweet) suspension cultures and root meristem cells were determined by pulse labelling with [ 3H]thymidine ([ 3H]TdR). Total cell cycle time for the suspension cultures was 27 h; 3 h in G1, 14 h in S, 6 h in G2, 2.2 ...
Mitosis and meiosis are both processes of eukaryotic cell division, with the same names used to describe different stages. What are the significant cellular and chromosomal events that occur during each stage of mitosis? What stage of cell cycle division results in...
A very recent analysis has revealed correlations between isochores from different families and the architectural features of chromosomes through the cell cycle. This leads to a unifying view of the genome organisation and chromosome architecture.

In squamous epithelia with a single layer of germinative cells, the age distribution of cells in the cell cycle is shown to depend on the direction of the mitotic axis (i.e. a line joining the nuclei of daughter cells) relative to the plane of the basal layer. When axes are in the ...
A stage of mitosis during which the duplicated chromosomes are segregated to different parts of the cell so they can serve as a complete genome for the next cell cycle. Anaphase is commonly thought of in two parts, A and B. During anaphase A, the chromosomes approach the ends of the mitot...
from the ancient Greek μετά (between) and φάσις (stage), is a stage of mitosis in the eukaryotic cell cycle in which condensed & highly coiled chromosomes, carrying genetic information, align in the middle of the cell before being separated into each of the two daughter cell...

During which phase in the cell cycle does mitosis happen? The phase of mitosis in which microtubules connect the centromere of each chromosome to the false of the spindle is? In meiosis how does prophase I differ from prophase II? At what point in mitosis does cytokinesis occur?
(APC/C), a ubiquitin ligase that plays an important role in cell cycle progression. Ectopic expression of the APC/C activators Cdh1 and Cdc20 reduced the levels of co-expressed E2F-1 protein. Co-expression of DP1 with E2F1 blocked APC/C-induced E2F1 degradation, suggesting that the E2F1/...
