Question

The two cells formed at the end of mitosis contain

• A. Same number of chromosomes as the original cell.
• B. Half the number of chromosomes as the original cell.
• C. Double the number of chromosomes or the original cell.
• D. None of the above.

Answer 1

The correct option is A

Same number of chromosomes as the original cell.

The correct option is A.

Explanation of the correct option

1. The equatorial division that occurs in cells that do not participate in reproduction is known as mitosis division.
2. After a cell divides, it produces two daughter cells that are identical to the mother cell in every way.
3. During phase S of the recurrent cell cycle, the genetic material of the cells doubles. As a result, the genetic material can be equally shared between the two daughter cells during mitosis.
4. Thus, the two daughter cells have the same number of chromosomes as the original cell.

Explanation of the incorrect options

Option B:

1. During meiotic cell division the daughter cells formed contain half the number of chromosomes as the original cell.
2. Haploid gametes are produced from diploid origional cells.

Option C:

1. During phase S of the cell cycle, the genetic content of the cells doubles.

Final answer:

The two cells formed at the end of mitosis contain same number of chromosomes as the original cell.
