Question

we need to make sure that you really know what you are talking about. cancer is associated with a mistake that occurs in the cell cycle. can you determine which description is something that happens during interphase and which one(s) is something that happens in mitosis?
put the following clues in the correct column. *

1. dna is duplicated.
2. dna condenses into visible sister chromatids instead of chromatin.
3. the normal functions of the cell occur, like growth and duplication of dna.
4. chromosomes align down the middle of the cell.
5. the nuclear envelope is present. dna is still in the form called chromatin.
6. sister chromatids separate and move to opposite ends of the cell.

Explanation:

• Interphase:
• During interphase, the cell is in a state of growth and preparation for division. DNA duplication (item 1) occurs in the S - phase of interphase. Also, the normal functions of the cell, including growth and DNA duplication (item 3), and the presence of the nuclear envelope with DNA in chromatin form (item 5) are characteristic of interphase.
• Mitosis:
• In mitosis, which is the process of cell division, DNA condenses into visible sister chromatids (item 2) in prophase. Chromosomes align down the middle of the cell (item 4) in metaphase. Sister chromatids separate and move to opposite ends of the cell (item 6) in anaphase.

Answer:

1. Interphase
2. Mitosis
3. Interphase
4. Mitosis
5. Interphase
6. Mitosis
