MICROANATOMY

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. The cell then leaves interphase, undergoes mitosis, and completes its division.

Detailed explanation-2: -Interphase is defined by three stages: the first gap phase (G1), the synthesis (S) phase, and the second gap (G2) phase.

Detailed explanation-3: -Purposes of mitosis: How do cells duplicate themselves, and why? In all complex multicellular organisms (eukaryotes), cell duplication occurs by a process called “mitosis” or cell division. Cells divide for two reasons: Growth.

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.
