TED-Ed: The immortal cells of Henrietta Lacks - Robin Bulleri

The video discusses the significance of HeLa cells, derived from Henrietta Lacks' tumor, which became the first immortal human cell line. These cells have been pivotal in scientific research, contributing to breakthroughs in cancer, virology, and genetics. Despite their importance, the ethical implications of using HeLa cells without consent are highlighted. HeLa cells have been used in various studies, including the development of the polio vaccine and understanding of HPV. Their unique properties, such as indefinite division, make them invaluable for research, although the exact reasons for their immortality remain unclear.

What was the unique feature of the tumor cells from Henrietta Lacks that made them valuable for research?

• They glowed under UV light.

• They were larger than normal cells.

• They could divide indefinitely.

• They were resistant to all known diseases.

Why is the HeLa cell line considered ethically controversial?

• They were sold to private companies for profit.

• They were used without the consent of Henrietta Lacks or her family.

• They were used to create biological weapons.

• They were patented without any research.

Which disease's vaccine development was significantly aided by HeLa cells?

• Influenza

• Polio

• Smallpox

• Tuberculosis

What discovery about chromosomes was made possible by HeLa cells?

• Human cells have 23 chromosomes.

• Chromosomes are made of RNA.

• Chromosomes are identical in all species.

• Human cells have 46 chromosomes.

What enzyme, first discovered in HeLa cells, helps cancer cells evade destruction?

• Ligase

• Polymerase

• Telomerase

• Helicase
