Briefly identify and describe the stages of interphase and mitosis associated with Figure 4.4 of your laboratory textbook.
During the four phases of interphase synthesis known as chromatin condensation and cell preparatory phase of division. The following phases take place in this process: gap 1 phase (G1) (cells grow/synthesize proteins required for mitosis activating the cell’s metabolism to break down carbohydrates/lipids transforming food into energy, this phase chromosomes consist of only one DNA molecule), S phase (replicates the cells DNA by copying the DNA molecules of each chromosome gaining 2 chromatids), and gap 2 phase (G2) (the cell grows/synthesizing more proteins, mitochondria grow and divide, transforms food into energy, cells store energy to utilize in mitosis, and mitosis phases (prophase, metaphase, anaphase, and telophase) (Khan Academy, 2016).
Mitotic phase of cell cycle include mitosis and cytokinesis. Animal cells consist of karyokinesis the separation of nucleus that is generally followed …show more content…
It can begin in anaphase or telophase, however, this is dependent upon the cell and finishes up after telophase. In animal cells cytokinesis is contractile. For example, pinching the cell depicting a purse with drawstring. The drawstrings represent a band of filaments made up of proteins known as actin and the pinch crease is recognized as being the cleavage furrow. However, plant cells do not have the ability to divide due to the cell wall being too stiff. Instead the cell plate develops down the center of the cell dividing it into 2 daughter cells. When cytokinesis is completed, too new cells are formed, both having complete sets of chromosomes same to those of the mother cell. The daughter cells are now able to start their own cellular lives with the possibilities of undergoing mitosis repeating the cycle (Khan Academy,
