Detailed explanation-1: -Final answer: G2 and M phase(s) of the cell cycle, the amount of DNA in a cell remains at 4C level if the initial amount is denoted as 2C.
Detailed explanation-2: -During a cell cycle the period from the end of the cell division to the beginning of DNA replication is known as G1 Phase. Sister chromatids are absent in the G1 phase. Sister chromatids are present in the G2 phase.
Detailed explanation-3: -A cell entering M phase has a 4N DNA content and finishes as two cells, each with an identical 2N complement of DNA. The complex sequence of changes that take place allows mitosis to be subdivided into prophase, prometaphase, metaphase, anaphase, and telophase.
Detailed explanation-4: -From the above information we can conclude that the amount of DNA in meiosis I is 10pg while in meiosis II the amount of DNA is 5 pg.
Detailed explanation-5: -The cell cycle is usually divided into four main phases. The first three phases are often referred to as the interphase, and they prepare the cell for the fourth phase-mitosis.
