This is when the genetic fibers within the cell’s nucleus, known as chromatin, begin to condense and become tightly compacted together. During interphase, the parent cell’s chromosomes are replicated, but they aren’t yet visible.
Prophase phase

WebbProphase is the first stage in mitosis. The nuclear envelope begins to break down and chromosomes condense and are now visible. Spindle fibers start to appear and centrosomes begin to move towards opposite poles. Prometaphase - Chromosomes continue to condense and are more visible. WebbWhen the chromosomes maneuver to the center of the cell, metaphase begins (Fig. 5). The spindle fiber network connects the centromere of the replicated chromosome to the outer part of each cell. The chromosomes now resemble the line of scrimmage of a football team, poised and waiting for some cellular signal to begin the next phase.

Prophase is the stage in mitosis where chromosomes, spindle, and polar bodies “appear“. From chromatin, the structure condenses into a chromosome. Remember that the result after S-phase is two copies of DNA in the form of two identical chains called sister chromatids. See the schematic diagram of a chromosome below.
Webb30 juli 2024 · Cells on the path to cell division proceed through a series of precisely timed and carefully regulated stages of growth, DNA replication, and division that produces two identical (clone) cells. The cell cycle has two major phases: interphase and the mitotic phase (Figure 1). During interphase, the cell grows and DNA is replicated.
