NEET BIOLOGY

Detailed explanation-1: -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-2: -During prophase II, the chromosomes condense, and a new set of spindle fibers forms. The chromosomes begin moving toward the equator of the cell.

Detailed explanation-3: -During prophase, the parent cell chromosomes-which were duplicated during S phase-condense and become thousands of times more compact than they were during interphase.

Detailed explanation-4: -Condensation of chromatin occurs during the prophase stage. In meiotic cell division, the mother cell divides twice after one round of replication. In meiosis, condensation occurs during prophase I which is long and complex stage.

Detailed explanation-5: -During S phase of the eukaryotic cell division cycle, newly replicated DNA is rapidly assembled into chromatin.
