PATHOLOGY

Detailed explanation-1: -Interphase is divided into the first growth (G1), Synthesis (S), and the second growth (G2) phases (figure 1). The growth phases are, as you may have suspected, for the growth of the cell, during the synthesis phase the DNA replication occurs in preparation for the second growth phase.

Detailed explanation-2: -The G1 phase stands for gap 1 and is when organelles replicate and the cell grows. The S phase stands for synthesis and is when DNA is replicated. The G2 phase stands for gap 2 and is when DNA is proofread and DNA damage is repaired.

Detailed explanation-3: -G1 phase (Gap 1)-Cellular contents excluding the chromosomes, are duplicated. II. S phase (DNA Synthesis)-Each of the 46 chromosomes are duplicated by the cell. III. G2 phase (Gap 2)-The Cell “double checks” the duplicated chromosomes for error, making any needed repair.

Detailed explanation-4: -G1 phase (G stands for gap) spans from the end of mitosis to the start of S phase. During G1 phase, cells check the external environment and the intracellullar state, and decide if they continue with the cell cycle or not.

Detailed explanation-5: -cell increases in size (gap 1, or G1, stage), copies its DNA (synthesis, or S, stage), prepares to divide (gap 2, or G2, stage), and divides (mitosis, or M, stage). The stages G1, S, and G2 make up interphase, which accounts for the span between cell divisions.
