Question
The division of the nucleus in eukaryotic cells.
Group of answer choices:
- cell division
- mitosis
- binary fission
- cytokinesis
- M phase
Solution
The division of the nucleus in eukaryotic cells is called mitosis. Here are the steps:
-
Interphase: This is the phase where the cell prepares for division. The DNA is replicated to ensure that the two new cells will have identical genetic material.
-
Prophase: The chromosomes condense and become visible. The nuclear envelope breaks down and the mitotic spindle begins to form.
-
Metaphase: The chromosomes align at the equator of the cell. The mitotic spindle, a structure made of microtubules, attaches to the chromosomes.
-
Anaphase: The sister chromatids (the two identical copies of a chromosome that were created during the DNA replication in interphase) separate and move to opposite ends of the cell.
-
Telophase: A new nuclear envelope forms around each set of chromosomes. The chromosomes decondense and become less visible.
