Chapter 11, Problem 2DAA
HeLa Cells Are a Genetic Mess HeLa cells can vary in chromosome number. Defects in proteins that orchestrate cell division result in descendant cells with too many or too few chromosomes, an outcome that is one of the ha1lmarks of cancer cells. The panel of chromosomes in FIGURE 11.9, originally published in 1989, shows all of the chromosomes in a single metaphase HeLa cell.
FIGURE 11.9 Karyotype of HeLa showing chromosomes in one cell.

DNA replication occurs between metaphase and anaphase, doubling the number of chromosomes. During metaphase, a cell contains identical copies of each chromosome, and then trans- forms into sister chromatids.
