Development, replication, and inheritance depend on the cell division cycle. A series of events is carried out in a cell leads to division and duplication. Two daughter cells get produced. Prokaryotes that lack a cell nucleus forms binary fission. Cells with a nucleus like eukaryotes the cell cycle are divided into three periods. Interphase, the (M) mitotic phase, and cytokinesis. In Interphase, the cell increases to accumulate nutrients needed for mitosis, preparing it for cell division and duplicating its DNA. Mitotic phase the cell splits itself into distinct daughter cells. The final stage cytokinesis the new cell is completely separated.
Mitosis, separate existing cells into new ones, of the responsibility for reproducing

The checkpoint control ensures that everything is available for DNA synthesis.
S: DNA synthesis replication occurs in this phase.
Gap 2: The gap between DNA synthesis and mitosis, the cell will continue to increase. Checkpoint control assures that everything is ready to enter the (M) mitotic phase and divide.
M: Cell growth stops at this stage, and cellular energy (2015, Wikipedia) focus on the orderly division into two daughter cells. Checkpoint in the middle of mitosis ensures that the cell is prepared to complete cell division.
Prophase: Chromatin in the nucleus begins to condense and becomes visible in the light microscope as chromosomes. (Arizona, 1997) Nuclear membrane dissolves. Microtubules attach to the kinetochores, and the chromosomes begin to move.
Prometaphase: Nuclear envelope has just integrated, allowing the micro tubes to interact quickly with the kinetochores on the chromosomes, which have just condensed
Metaphase: Spindle fibers align the chromosomes along the middle of the cell nucleus. (Arizona, 1997) The metaphase plate the organization help ensure that is the future phase. When the chromosomes divide, each nucleus will receive one copy of each

Determine how many phases of mitosis (prophase, metaphase, anaphase, and telophase) under a microscope at 400x magnification.
Looking, under the microscope of an onion root tip. There are stages of mitosis in the cells. How many kinds of stages of the cycle can be detected?
When examined an onion root tip organism observed under a microscope, most cells out of 50 that is not Interphase. Prophase will be observed most out of the cell cycle.
