Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]

Which of the following do chromosomes become visible, centrioles move to opposite ends, nuclear membrane breaks down, & spindle fibers appear?

A	Prophase
B	Metaphase
C	Telophase
D	Anaphase

Explanation:

Detailed explanation-1: -Thus, the correct answer is ‘Prophase. ‘

Detailed explanation-2: -Prophase: chromosomes are visible, nuclear membrane breaks down, spindle fibers begin to form.

Detailed explanation-3: -Anaphase I: In anaphase I, the attachment of the spindle fibers is complete. The homologous chromosomes are pulled apart and move towards opposite ends of the cell.

Detailed explanation-4: -At the beginning of the first mitotic stage, prophase, the thread-like doubled chromosomes contract and become visible. The two centrioles move to opposite sides of the nucleus. At the same time, the nuclear membrane begins to break down.

Detailed explanation-5: -Centrioles begin moving to opposite ends of the cell and fibers extend from the centromeres. Some fibers cross the cell to form the mitotic spindle. The nuclear membrane dissolves, marking the beginning of prometaphase. Proteins attach to the centromeres creating the kinetochores.
