|
anaphase only

|
prophase, anaphase and metaphase
|
|
|
metaphase only
|
|
|
anaphase and interphase

Explanation:
Detailed explanation-1: -Chromosomes become visible during prophase. Chromatin is in its least condensed stage during the interphase stage. It begins its condensation during the prophase stage and is visible until the end of cell division.
Detailed explanation-2: -During prophase, the complex of DNA and proteins contained in the nucleus, known as chromatin, condenses. The chromatin coils and becomes increasingly compact, resulting in the formation of visible chromosomes.
Detailed explanation-3: -Anaphase. At the end of metaphase, the chromosomes are lined up in the centre of the cell. They are still visible as two sister chromatids joined at the centromere.
