Which mitosis phase happens most quickly?
When Mitosis Occurs Most Rapidly
This means, in humans, the fastest rate of mitosis happens in the zygote, embryo and infant stage. A high rate of mitosis is required to grow and repair tissue, such as in human lymph nodes and bone marrow.
What phase occurs immediately following mitosis?
The mitotic phase follows interphase. Mitosis is nuclear division during which duplicated chromosomes are segregated and distributed into daughter nuclei. Usually the cell will divide after mitosis in a process called cytokinesis in which the cytoplasm is divided and two daughter cells are formed.
Which is the shortest phase?
Note: The shortest phase of the cell cycle is the Mitotic phase (M phase) and the longest phase of the cell cycle is G-1 phase.
During what stage does G1 S and G2 phase happen?
Interphase. G1, S and G2 phases are all cumulatively referred to as interphase involving the growth of a cell and the replication of its DNA.
What happens during G1 phase?
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 this time, the cell grows in preparation for DNA replication, and certain intracellular components, such as the centrosomes undergo replication.
What are the 4 phases of mitosis?
These phases are prophase, prometaphase, metaphase, anaphase, and telophase.
What is the shortest phase of the cell cycle?
The shortest stage of the cell cycle is called cytokinesis (division of the cytoplasm). In cytokinesis, the cytoplasm and its organelles divide into two daughter cells. contains a nucleus with an identical set of chromosomes.
Why does interphase take so long?
The reason that interphase takes so long is because a lot is happening during interphase. Interphase is traditionally divided into three smaller sub-stages. … It takes about eight to ten hours for a typical mammalian cell to complete DNA synthesis, and this is the main reason why interphase is so lengthy.
