Question:
Which of the following statements about eukaryotic asymmetric cell division is NOT correct?
Which of the following statements about eukaryotic asymmetric cell division is NOT correct?
Show Hint
Asymmetric division = equal chromosomes, unequal cytoplasmic determinants.
Updated On: Sep 8, 2025
- Chromosomes are unequally distributed in the daughter cells
- Chromosomes are equally distributed in the daughter cells
- RNA and proteins are unequally distributed in the daughter cells
- Cytoplasmic contents are unequally distributed in the daughter cells
Show Solution
Verified By Collegedunia
The Correct Option is A
Solution and Explanation
Step 1: Define asymmetric cell division.
In asymmetric cell division, daughter cells receive equal genetic material (chromosomes), but they differ in cytoplasmic determinants such as RNA, proteins, and organelles. This leads to functional diversity.
Step 2: Evaluate options.
- (A) Incorrect. Chromosomes are always equally distributed in daughter cells during normal mitosis/meiosis. Unequal distribution would cause aneuploidy, not asymmetry.
- (B) Correct statement. Chromosomes are equally distributed.
- (C) Correct statement. RNA and proteins are unequally distributed.
- (D) Correct statement. Cytoplasmic contents differ between cells.
Final Answer: \[ \boxed{\text{Chromosomes are unequally distributed in the daughter cells (NOT correct).}} \]
