Question
Chapter 4.5, Problem 1CS
Summary Introduction
To determine: The effects of cell division on chromosome territories.
Introduction: Two daughter cells are produced from one parent cell through cellular division. Cell division is a part of the cell cycle. Vegetative division of eukaryotic cells is referred to as mitosis and reproductive division of eukaryotic cells is referred to as meiosis. Genetically identical daughter cells are produced through mitosis, which is not the case during meiosis.

Question:
If a certain species has a DNA content of 5 picograms in each diploid cell's nucleus when the cell in in G1 of the cell cycle, what would be the expected DNA content (in picograms) of a diploid cell (from the same species) in mitotic prophase? Explain your reasoning. Consider ploidy changes and/or chromosome form changes, if applicable, when explaining your reasoning.
