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 by cytokinesis separation of cytoplasm (Khan Academy, 2016).

Mitosis consists of four basic phases: prophase, metaphase, anaphase, and telophase. These phases transpire in a strict order and cytokinesis (the process of dividing the cell substances to make two new cells) begins in anaphase or telophase (Khan Academy, 2016).

Prophase consists of cells breaking down certain structures and building up others in order for division of the chromosomes to take…
