HeLa was key to mapping the human genome. In fact, it was a HeLa cell which was used to determine that humans have 46 chromosomes. HeLa cells went to space in both American and Russian satellites ...

Chromosome number and nuclear DNA content of two cloned HeLa cell lines were analysed by quantitative Feulgen reaction microspectrophotometry, ultra-rapid microfluorometry and chromosome counting.

HeLa cells are unique in many ways. The normal human cells contain 46 chromosomes, while HeLa cells have been shown to contain between 75-82 chromosomes, and cells vary considerably between ...
