For most dividing cells in a diploid organism, the time spent in mitosis is approximately 4% of the total time of the cell cycle. In a population of continually dividing cells isolated from this organism, most of the cells would... A.have highly condensed chromatin. B.  be in interphase (G1 or S or G2). C. be in mitosis. D.  be in meiosis.

Block the production of ATP by the ribosomes. c. Interfere with the ability of the fetal cells to replicate. d. Cause nondisjunction of the chromosomes, causing fetal cells to have two of each chromosome instead of three.
