NEET PG DENTAL EXAM

Detailed explanation-1: -Metaphase. During metaphase, spindle fibers attach to the centromere of each pair of sister chromatids (see Figure below). The sister chromatids line up at the equator, or center, of the cell. This is also known as the metaphase plate.

Detailed explanation-2: -In metaphase, chromosomes are lined up and each sister chromatid is attached to a spindle fiber. In anaphase, sister chromatids (now called chromosomes) are pulled toward opposite poles. In telophase, chromosomes arrive at opposite poles, and nuclear envelope material surrounds each set of chromosomes.

Detailed explanation-3: -During metaphase II, the centromeres of the paired chromatids align along the equatorial plate in both cells.

Detailed explanation-4: -Answer and Explanation: The correct answer: The phase of mitosis in which the chromosomes line up on the equator of the cell is e. metaphase.
