Detailed explanation-1: -Then, at a critical point during interphase (called the S phase), the cell duplicates its chromosomes and ensures its systems are ready for cell division.
Detailed explanation-2: -During interphase, the cell grows and makes a copy of its DNA.
Detailed explanation-3: -Because of this, DNA makes a copy of itself in a process known as replication during interphase, a stage that occurs before cells divide.
Detailed explanation-4: -Initially in G1 phase, the cell grows physically and increases the volume of both protein and organelles. In S phase, the cell copies its DNA to produce two sister chromatids and replicates its nucleosomes. Finally, G2 phase involves further cell growth and organisation of cellular contents.
Detailed explanation-5: -Cells must replicate their DNA before they can divide. This ensures that each daughter cell gets a copy of the genome, and therefore, successful inheritance of genetic traits.
