Question 9

Determine whether each of the following events is characteristic of mitosis, meiosis, or both. Answers may be used more than once.
-prophase
A)
B)
C)
D)

Accepted Answer

Prophase is the initial stage of mitosis where chromosomes begin to condense and the mitotic spindle begins to form.

Answer: C 
 Sister chromatids are joined at the centromere during prophase.

Answer: G 
 The mitotic spindle is formed during prophase in preparation for the separation of sister chromatids during later stages of mitosis.

Answer: H 
 A chromosome in prophase is composed of two sister chromatids joined at the centromere.

Answer: I 
 In some eukaryotic cells, chromosomes are present in pairs during prophase and move toward the spindle poles as the mitotic spindle forms.
