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. How many extra chromosomes does this cell have, compared to a normal human body cell?

How many extra chromosomes does this cell have, compared to a normal human body cell?

Summary Introduction

To determine: The extra chromosomes HeLa cells have to compare to the normal human body cell.

Concept introduction: HeLa cell is the oldest and most commonly used cell line which was derived from the cervical cancer cells. HeLa cells differ from the normal cells in many ways. These cells have the ability to contaminate other cell lines. These cells have furthered the understanding of cancer, HIV, and the cells in general. It is still used widely to grow viruses and to test anti-tumor medicines.

Explanation of Solution

A normal human cell has a chromosome number of 46. The HeLa cells have an extra 36 chromosomes when compared to the normal human body cells...
