Question
Which of the following occurs during prophase?Group of answer choicesThe alignment of chromosomes at the equator of the cell.The uncoiling of chromosomes.The chromosomes are pulled away from each other.The condensing of chromosomes.
Solution
During prophase, the condensing of chromosomes occurs. This is the stage where the chromatin condenses into a highly ordered structure called chromosomes. The centrosomes move to the opposite ends of the cell and start to form the mitotic spindle. The nuclear envelope also breaks down during this phase. The other options mentioned occur in different stages of cell division. The alignment of chromosomes at the equator of the cell occurs during metaphase, and the chromosomes being pulled away from each other happens during anaphase. The uncoiling of chromosomes occurs during telophase.
