The Cell Cycle
The Prokaryotic cells reproduce by a process that is called binary fission. The DNA in cells is contained by one chromosome called a plasmid that is in the cytoplasm. The reproductive process starts with a copy of the chromosome. The new chromosome attaches itself to the plasma membrane and the two chromosomes spread to opposite ends of the cell. The plasma membrane in the middle of the cell grows inward until it closes to separate the cell into two parts, each full of genetic material. The cell then fissions at the center, forming two new daughter cells.
1.)there are three different stages known as G1,G2, and S in the interphase
2.)G1 G2 and s are the three stages which make up what is called interphase.
G1= cells grow bigger in size the produce rna.G1's job is to make sure cell is ready for dna synthesis.
S: during this the dna in the cell are copied, so it now has 2 identical protein chains, one for each daughter cell.
Gap 2 - Basically the same as G1 just known as the G2 checkpoint.
3.) DNA replicates or duplicates in the S phase
4.) it happens after interphase when G2 has all ready occurred.
5.)Cells that produce asexually go through the mitosis
6.) cells that produce sexually do not go through the mitosis
7.) The Interphase, Prophase, Metaphase, Anaphase, Telophase, and cytokinasis.
8.)The interphase stage (the longest stage) is where the DNA is duplicated (in the S stage of interphase to be precise, the interphase stage is divided into G1, S, and G2 phases). In prophase, the nuclear envelope breaks down and a spindle forms between to centrioles. This is also the stage where the chromosomes are maximally condensed. In metaphase the chromosomes align along the equator of the cell. In anaphase, the chromatids (duplicated chromosomes) are separated. In telophase the two cells begin to pull apart, but with plant cells, a cell wall is built in between the two cells.
9.)the chromosomes of a parent cell are duplicated and given to the two daughter cells during cell division, the structure of the chromosomes changes.
10.)Cytokinesis is the outcome of mitosis when mitosis or cell division happens when all the DNA and proteins are in the cytoplasm leading to 2 new cells and cytokinesis happens in certain phases of mitosis like anaphase and telophase.
