Question

which statement best explains one reason why the cells produced from meiosis are different from the cells produced during mitosis?
during meiosis, the genetic material is not copied, while in mitosis, the genetic material is copied.
during meiosis, dna is intentionally mutated, producing daughter cells with new dna sequences, while in mitosis, the dna does not mutate.
during meiosis, one cell divides once into two cells, while in mitosis, the cell divides twice into four cells.
during meiosis, sections of dna trade places, producing daughter cells different from the parent cells, while in mitosis, the daughter cells are identical.

Explanation:

• In meiosis, crossing - over (sections of DNA trade places) occurs during prophase I. This genetic recombination leads to daughter cells with different genetic combinations from the parent cell.
• In mitosis, the daughter cells are genetically identical to the parent cell as there is no such recombination event.
• Option 1 is incorrect because genetic material is copied in both meiosis and mitosis.
• Option 2 is incorrect as mutation is not an intentional and regular part of meiosis in the way described.
• Option 3 is incorrect because in meiosis, one cell divides twice into four cells and in mitosis, one cell divides once into two cells.

Answer:

During meiosis, sections of DNA trade places, producing daughter cells different from the parent cells, while in mitosis, the daughter cells are identical.
