Explanation:
All of the following activities occur in the course of prophase in mitosis except crossing over.
Mitosis may be divided into 4 stages: prophase, metaphase, anaphase, and telophase.
Throughout prophase, the chromatids condense into chromosomes, thereby making them seen. The mitotic spindle is a structure composed of microtubule proteins that segregate the chromosomes in mitosis. This shape is formed in prophase.
In Prophase homologous pairs of chromosomes are paired together. In metaphase, these chromosomes are lined up at the equator of the mobile, and sister chromatids are connected to the spindle fiber.
Crossing over (or recombination) is the alternate of genetic cloth between non-sister chromatids that occurs in the course of prophase I of meiosis.
In end, condensation of DNA, the pairing of chromosomes, and, spindle formation arise for the duration of prophase, while crossing over occurs in prophase I of the meiotic cellular department (choice B).
