What happens during prophase?
A.Chromosomes condense and the spindle begins to form
B.Sister chromatids separate
C.Nuclear envelopes reform
D.DNA replicates
Explanation
Core Concept
During prophase, chromosomes condense and the mitotic spindle begins to form. In many animal cells, centrosomes help organize spindle microtubules and move apart, whereas plant cells can organize a spindle without typical centrosomes. The general AP concept is spindle formation and chromosome preparation for segregation.
Correct Answer
AChromosomes condense and the spindle begins to form
