For a diploid mouse cell (40 chromosomes), state how many copies of each are present at the following cell cycle stages:

Cell cycle stage

Number of chromosomes per cell

Number of sister chromatids per cell

Number of centromeres per cell

Number of chromosome copies attached to each centromere

G1 phase

G2 phase

Prophase

Anaphase

A researcher has synchronized two different E. coli cultures so that all of the cells enter cell division simultaneously. One culture is wild-type E. coli cells, and the other culture is a mutant E. coli that does not have the gene for Dam methylase. He isolates the DNA from both wild-type and mutant E. coli 20 minutes after replication is complete. What is the methylation state for each strain of E. coli? What would be the methylation state for each bacterial strain if you isolated the DNA immediately after replication termination?
