Questions: 3. Find a cell that is in prophase. Prophase is characterized by the dark, spotty nucleus and the absence of nuclear envelope. Asters may also be seen. Draw one cell. - Why is the nucleus stained dark? The nucleus appears dark during prophase because the chromatin condenses into tightly packed chromosomes. - At this stage, each chromosome contains how many copies of DNA molecule? 4. Find a cell that is in metaphase. Metaphase is characterized by the arrangement of dark-stained chromosomes on metaphase plate. Draw one cell. - How many asters should one cell have? - Can you see spindle fibers? 5. Find a cell that is in anaphase. Anaphase is characterized by two somewhat parallel dark bands resulting from separation of sister chromatids. Draw one cell. - What attach to the centromere and pull daughter chromosomes to opposite poles?
