During S phase the amount of DNA in the cell doubles because chromosomes are duplicated. As a result, the amount of DNA found in a cell in G2 is significantly higher than that of a cell in G1.
The process of cell division, called cell cycle, has four major parts called phases. The first part, called G1 phase is marked by synthesis of various enzymes that are required for DNA replication. The second part of the cell cycle is the S phase, where DNA replication produces two identical sets of chromosomes.he term cell growth is used in the contexts of cell development and cell division (reproduction). When used in the context of cell division, it refers to growth of cell populations, where a cell, known as the mother cell, grows and divides to produce two  daughter cells  (M phase).
