The wording in the book is confusing me. The first answer is 20 and the second is also 20?The book does say interphase is the longest 1.1 If a cell has 20 chromosomes during G, of interphase, how many chromosomes would be present during prophase?1.2 How many chromosomes would each of the two new cells have that resulted from the mitotic division of this cell?1.3 The different stages of mitosis are not of equal duration; some stages are relatively long while others are quite brief. Becausethe frequency of cells in each stage is proportional to the relative duration of that stage, you can estimate the relative length ofa stage by counting the number of cells arrested in that particular stage. Based on. the number of cells you observed in eachstage of mitosis (excluding interphase), which stage do you think takes the longest time to complete? (You may want to reviewthe slide again and count a random sample of 100 cells to answer this question.)

Question

100%

The wording in the book is confusing me. The first answer is 20 and the second is also 20?

The book does say interphase is the longest

1.1 If a cell has 20 chromosomes during G, of interphase, how many chromosomes would be present during prophase?
1.2 How many chromosomes would each of the two new cells have that resulted from the mitotic division of this cell?
1.3 The different stages of mitosis are not of equal duration; some stages are relatively long while others are quite brief. Because
the frequency of cells in each stage is proportional to the relative duration of that stage, you can estimate the relative length of
a stage by counting the number of cells arrested in that particular stage. Based on. the number of cells you observed in each
stage of mitosis (excluding interphase), which stage do you think takes the longest time to complete? (You may want to review
the slide again and count a random sample of 100 cells to answer this question.)
