How does the cell prepare for mitosis Do all eukaryotic cell

How does the cell prepare for mitosis? Do all eukaryotic cells undergo mitosis at some point? Explain. Describe the products of mitosis. How many cells result? Are they like the parent cell or different?

Solution

3. Cell makes all the preparations for mitosis during interphase. During interphase the cell increases in size by accumulating cytoplasm and multiplication of cell organelles, builds new material for the daughter cells.

The interphase is divided into 3 stages;

G1 phase: during this phase, cell increases in size by multiplying cell organelles, accumulation of cytoplasm, synthesis of protiens and nucleotides, enzymes. In G1 the cell makes all the preparations to replicate its chromosomes.

S phase: During this stage, cell undergoes chromosome replication. DNA of chromosomes is duplicated so that each chromosome now consists of two sister chromatids.

G2 phase: during this phase cell undergoes furthur growth. The cell enlarges in size, and makes more organelles like ER, mitochondria, etc needed for the daughter cells.
