_______ is the stage of mitosis characterized by the physical separation of ________ chromatids.
- A
Interphase, daughter
- B
Telophase, genetic
- C
Metaphase, sister
- D
Anaphase, sister
Anaphase is the correct answer because it is the stage in mitosis where sister chromatids are physically separated and move towards opposite poles of the cell. This separation is facilitated by the shortening of spindle fibers. In contrast, during Metaphase, chromosomes only align at the cell's equator without separation. Telophase involves the reformation of the nuclear envelope around the separated chromatids, and Interphase is the preparatory phase for cell division, not part of mitosis itself.
Interphase is not part of mitosis; it is the period when the cell prepares for division. 'Daughter' refers to the resulting cells after cell division, not chromatids.
In Telophase, the chromatids have already reached the poles and the nuclear envelope reforms. 'Genetic' is a broad term and does not specifically refer to chromatids.
In Metaphase, chromosomes align at the cell's equator, but chromatids do not separate. 'Sister' refers to chromatids, but the actual separation happens later in Anaphase.
Anaphase is characterized by the separation of sister chromatids, which are pulled apart to opposite poles of the cell.
