Explanation:
Detailed explanation-1: -In a cell which is not dividing, DNA is present as part of chromatin material. These are called chromatin because they get coloured when they are stained. Chromatin material is visible as an entangled mass of thread-like structures.
Detailed explanation-2: -M phase. During the mitotic (M) phase, the cell divides its copied DNA and cytoplasm to make two new cells. M phase involves two distinct division-related processes: mitosis and cytokinesis.
Detailed explanation-3: -DNA replication is the process by which the genome’s DNA is copied in cells. Before a cell divides, it must first copy (or replicate) its entire genome so that each resulting daughter cell ends up with its own complete genome.
