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 is a process that occurs during thecell cycle.The role of mitosis in the cell cycle is to replicate the genetic material in an existing cell—known as the “parent cell”—and distribute that genetic material to two new cells, known as “daughter cells.”In order to pass its genet...
Mitosis is part of the cell cycle where one cell divides into two identical daughter cells. Both daughter cells will have the same number of chromosomes due to replication of DNA earlier in the cell cycle.
For the cells of the body not involved in reproduction, or the somatic cells, mitosis represents a part of the cell cycle in which somatic cells make copies of DNA to produce two new identical daughter cells. The two main parts of the cell cycle include interphase and mitosis. During ...

The G1, S and G2phases are collectively termed interphase. The rest of the cell cycle is concerned with cell division – mitosis in somatic cells, meiosis in the specialized cells of gonads. The stages of mitosis and meiosis are collectively called the M phase, potentially introducing confusion...
The cell cycle is composed of 4 different stages: G1, S, G2, and M. During the G1 phase, the cell expands in size, doubling its organelle content. After that, the genetic material of the cell is duplicated via deoxyribonucleic acid (DNA) replication. It ensures that genetic material ...
The phase of cell division in which chromosomes align on the spindle equator halfway between the spindle poles is ___. A. metaphase. B. prophase. C. telophase. D. anaphase. What are the phases in the cell cycle and how do they relate to mitosis? Cross...
The highly condensed chromosomes in a dividing cell are known as mitotic chromosomes. During the portion of the cell cycle when the cell is not dividing, the chromosomes are extended and much of their chromatin exists as long, thin tangled threads in the nucleus (Fig. 5.2). Sign in to ...
