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.

Expert Solution
Step 1

Mitosis cell division is the type of cell division that occurs in the somatic cells and all the other cells except the germ cells. This cell is known as equational cell division. During this process the cell divides into two daughter cells with equal amount of DNA as the parent cell itself. The four phases of mitosis cell division are:

  • Prophase
  • Metaphase
  • Anaphase
  • Telophase

These four phases mark the division of DNA content in the daughter cells. After the division of the DNA which is known as karyokinesis, the cell undergoes cytokinesis in which the cytoplasm and other cell contents are divided into the two daughter cells.
