What are Hela cells? Why are Hela cells appropriate for karyotype experiments?

Hela cells are an immortal cell line used in scientific research. These cells were derived from a cervical cancer biopsy taken from a woman named Henrietta Lacks in 1951. Since then, these cells have been extensively used in various scientific studies, including cancer research, drug discovery, and virology. Hela cells are appropriate for karyotype experiments because they have a stable chromosome number and structure. The karyotype is the number and appearance of chromosomes in the cell. Hela cells have 46 chromosomes, which is the normal human diploid chromosome number. Since these cells have a stable chromosome number and structure, they can be used as a reference for comparative karyotype studies where researchers can compare the karyotypes of other cells with those of Hela cells. Additionally, Hela cells divide rapidly, providing a large population of cells for analysis, making them ideal for karyotype experiments.
