Mitosis questions?

1. During mitosis, a double stranded chromosome is attached to a spindle fiber at the a) centriole b) centromere c) centrosome 4)cell plate (i would say its a but not 100 percent sure)


2. After mitotic cell division, the number of chromosomes in each daughter cell as compared to the parent cell is a) same b)1/4 as great c) 1/2 as great d) twice as great


3. As a result of mitosis, the chromosome number within each cell of a developing embryo will a) be halved b) be doubled c)remain the same d) vary at random.


4. When mitosis has been completed, the quantity of DNA in each daughter cell nucleus will be a)half as much as in the parent nucleus b)the same as in the parent nucleus c) twice as much as in the parent nucleus d) variable, depending on the activity within the cytoplasm during interphase.


5. Which would result if cytoplasmic division did not accompany mitosis? a)two cells, each with 1 nucleu b)one cell with no nucleus c) two cells, each lacking a nucleus d) one cell with 2 nuclei.

Mitosis questions?
1. centromere (not centrioles - those are the paired structures at the poles of the spindle. The centromere is the part that attaches the two sister chromatids together)


2. same


3. same


4. same


5. one cell with two nuclei


6. not able to reproduce
