Question

Quizplus · Accepted Answer

The correct number of chromosomes in human cell nuclei is 46. This is because each human cell has 23 pairs of chromosomes, for a total of 46. Option A, 42, is incorrect because it is not the correct number of chromosomes in human cells. Option B, 45, is also incorrect as humans do not typically have an odd number of chromosomes. Option D, 49, is not correct either because 49 chromosomes would suggest there are more than 23 pairs, which is not the case in humans. Option E, 50, is also not correct because it would indicate more than 23 pairs.
