During anaphase, the cell begins to elongate as the sister chromatids are pulled apart toward opposite poles of the cell. The spindle fibers attached to the chromatids shorten, while those not attached to chromosomes lengthen, pushing the poles further apart. This elongation is crucial for preparing the cell for division.
Chromosomes are no longer visible during the interphase stage of the cell cycle, specifically in the G1, S, and G2 phases, when they are in a relaxed, uncoiled state called chromatin. However, if referring specifically to mitosis, chromosomes become less distinct and start to decondense during telophase, as the nuclear envelope begins to reform. In this stage, they are difficult to distinguish individually.
No, a cell is not the largest during anaphase. During anaphase of mitosis, the sister chromatids are pulled apart toward opposite poles of the cell, but the overall size of the cell does not significantly increase at this stage. The cell typically reaches its maximum size during the interphase stage, particularly in the G2 phase, before mitosis begins.
During the synthesis stage (S phase) of mitosis, a cell replicates its DNA, ensuring that each daughter cell will receive an identical set of chromosomes. This process involves the unwinding of the double helix and the synthesis of new complementary strands by DNA polymerase. Additionally, the cell begins to produce proteins and organelles necessary for cell division, preparing for the subsequent phases of mitosis.
When the M phase, or mitosis, begins during the cell cycle, it starts with prophase. Prophase is the first stage of mitosis where chromatin condenses into visible chromosomes, the nuclear membrane breaks down, and the mitotic spindle begins to form.
Prophase
the stage before mitosis is called interphase and majority of the time the cell has is spent in interphase. during interphase the cell acquires nutrients and the DNA replicates.

In this stage, they are difficult to distinguish individually.
Before mitosis begins, the cell undergoes a period of growth and DNA replication during interphase. This is when the cell duplicates its genetic material and prepares for division. It is a crucial step to ensure that the resulting daughter cells have the correct number of chromosomes.
