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.

a. What is the diploid number of chromosomes for a human? b. What is the haploid number of chromosomes for a human? Which cells are considered diploid, gametes or somatic cells? C. d. Which cells are considered haploid, gametes or somatic cells?

which of the following events occurs during anaphase B in a mitotic cell a. lengthening of the overlap microtubules  b.  Shortening of the overlap microtubules c. Shortening of the overlap microtublues d. Shortening of the astral microtubules e. Lengthening of the kinetochore microtubules

The use of chemotherapy drugs that interfere with the cell cycle is avoided during pregnancy. This is because they: a. Ingibit the synthesis of proteins by the mitochondria. b. 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.
