Which cells divide the fastest?
Basal cells divide faster than needed to replenish the cells being shed, and with each division both of the two newly formed cells will often retain the capacity to divide, leading to an increased number of dividing cells.
Which cell cycle is the shortest?
Which phase of the cell is longest?
Where in the body does anaphase occur?
Anaphase of Meiosis takes place in the sperm and the ovum cells whereas Anaphase of Mitosis can take place in all cells of the body. In anaphase, the spindle fibres pull homologous chromosomes that are arranged at the equatorial plate, towards opposite poles of the spindle.
Why is it called anaphase?
Anaphase (from the Greek ἀνά, “up” and φάσις, “stage”), is the stage of mitosis after the process of metaphase, when replicated chromosomes are split and the newly-copied chromosomes (daughter chromatids) are moved to opposite poles of the cell.
What happens during late anaphase?
Anaphase typically is a rapid process that lasts only a few minutes. When the chromosomes have completely migrated to the spindle poles, the kinetochore microtubules begin to disappear, although the polar microtubules continue to elongate.
Is anaphase a G1?
During anaphase, DNA is segregated into two which separates the nucleolus (black sphere) from DNA. As nuclei finish their transition into G1 all proteins of the parental nucleolus are re-imported into daughter nuclei to form a new nucleolus within each daughter G1 nucleus.
What happens during G1 cell cycle?
G1 phase. G1 is an intermediate phase occupying the time between the end of cell division in mitosis and the beginning of DNA replication during S phase. During G1, the cell reviews the cellular environment and the cell size to ensure that the conditions are appropriate to support DNA replication.
What is M phase in cell cycle?
M stands for mitosis. This is where the cell actually partitions the two copies of the genetic material into the two daughter cells. After M phase completes, cell division occurs and two cells are left, and the cell cycle can begin again.
