Which observation below provides evidence that differentiated cells retain all the genes of developing cells?
A)Developing cells have many mRNA transcripts that can hybridize with DNA from mature cells.
B)Differentiated cells generally synthesize a specific group of proteins.
C)Nuclei from mature cells can direct the development of an entire individual.
D)Not all mature cells are capable of differentiation.

Question

Quizplus · Accepted Answer

The observation that nuclei from mature (differentiated) cells can direct the development of an entire organism provides evidence that differentiated cells retain all the genes of developing cells. This is because for an entire organism to develop from the nucleus of a single differentiated cell, that cell must have contained all of the genetic information needed for the organism's development. Options A and B do not provide evidence that differentiated cells retain all the genes of developing cells, and option D is not relevant to the question.
