PATHOLOGY

Detailed explanation-1: -A cell spends most of its time in what is called interphase, and during this time it grows, replicates its chromosomes, and prepares for cell division.

Detailed explanation-2: -At the molecular level, however, interphase is the time during which both cell growth and DNA replication occur in an orderly manner in preparation for cell division. The cell grows at a steady rate throughout interphase, with most dividing cells doubling in size between one mitosis and the next.

Detailed explanation-3: -During interphase (1), chromatin is in its least condensed state and appears loosely distributed throughout the nucleus. Chromatin condensation begins during prophase (2) and chromosomes become visible. Chromosomes remain condensed throughout the various stages of mitosis (2-5).

Detailed explanation-4: -In G1, cells accomplish most of their growth; they get bigger in size and make proteins and organelles needed for normal functions of DNA synthesis. Here, proteins and RNAs are synthesized, and, more especially the centromere and the other components of the centrosomes are made.

Detailed explanation-5: -A cell grows during the G1 phase of the cell cycle. During this phase, more organelles are produced, a high amount of protein synthesis occurs and the volume of the cytoplasm increases. The cell continues to grow further in the G2 phase.
