Which of the following statements is TRUE?
A) Each new cell receives half of the number of chromosomes in the original cell.
B) Each new cell receives copies of all the original chromosomes.
C) If the original number of chromosomes was 46, each new cell will have 23.
D) The sister chromosomes are not identical due to breakages in the DNA.
E) All chromosomes are duplicated except the sex chromosomes.

Question

Quizplus · Accepted Answer

During cell division, each new cell receives an exact copy of all the original chromosomes through the process of DNA replication. This is essential for maintaining the correct number of chromosomes in daughter cells. Option A is incorrect because the number of chromosomes in daughter cells is equivalent to the number in the original cell. Option C is also incorrect because if the original number of chromosomes was 46, each new cell should also have 46 chromosomes. Option D is incorrect because sister chromatids are identical and contain the same genetic information, barring any rare mutations or genetic anomalies. Option E is incorrect because all chromosomes, including the sex chromosomes, undergo duplication during the cell cycle.
