Answer:
Mitosis, specifically telophase
Step-by-step explanation:
Cells undergo cell division in order to proliferate and grow the population. Cells first duplicate their DNA. There are 4 stages of mitosis: prophase, metaphase, anaphase, telophase
During prophase, the DNA condenses, forming visible chromosomes and a special structure called a spindle forms. During metaphase, the chromosomes line up in the centre of the cell, pairing up with their homologous partner. During anaphase, the spindles attach to the centre of the cell and the chromosomes are pulled away to opposite ends of the cell.
During telophase, the spindle disappears and the chromosomes decondense. At the end of telophases, cytokinesis occurs, splitting the cell into two daughter cells, each carrying the same genetic information as was in the cell prior to replication of the DNA.
