The number of hypothetical animal geneticus introductus is 2n=36. Each diploid nucleus contains 3 ng of DNA in G1.

a) What amount of DNA is contained in each nucleus at the end of S phase?

b) Explain why a somatic cell of Geneticus introductus has the same number of chromosomes and the same amount of DNA at the beginning of mitotic prophase as one of these cells does at the beginning of prophase I and mitosis.

c) How many chromosomes and amount of DNA present per cell at the end of each stage: telophase I, Mitotic anaphase, and Telophase II.
