Web5 sep. 2024 · In mitosis, there are basically 4 phases, namely prophase, metaphase, anaphase, and telophase. During prophase, the chromosomes condense and become visible. The nuclear envelope breaks down and the nucleolus disappears. The centriole moves towards the opposite poles of the cell. During metaphase, the mitotic spindle is … WebDuring this stage of mitosis, the chromosomes line up in the middle of the cell along the equator . Each chromosome attaches itself to a spindle fiber. 4. Anaphase. During anaphase the chromatids are pulled apart by the spindle and move to opposite sides of the cell. 5. Telophase. Now that the chromosomes are separated, two nuclei are formed. inc. richard sortino

WebWhich process has chromosome replication? During the DNA synthesis (S) phase, the cell replicates its chromosomes. During the mitosis (M) phase, the duplicated chromosomes are segregated, migrating to opposite poles of the cell. The cell then divides into two daughter cells, each having the same genetic components as the parental cell.

Cell division entails making more cells through duplication of the one cell’s contents and then splitting this cell into two … WebThe dividing mother cell must provide both daughter cells with a complete set of chromosomes. To do this, the stem cell must duplicate its chromosomes before cell division. This duplication is carried out during the synthesis phase of the cell cycle. The chromosomal duplication is then part of a duplicated chromosome.

WebDuring every cell division, a cell must duplicate its chromosomal DNA through a process called DNA replication. The duplicated DNA is then segregated into two daughter cells that inherit the same genetic information. This process is called chromosome segregation. What phase do chromosomes replicate?
