Explanation:

HeLa cells are a type of immortal cell line. They were derived from cervical cancer cells of Henrietta Lacks in 1951. These cells have been widely used in scientific research due to their ability to divide indefinitely in culture. CDK (cyclin - dependent kinase) is an enzyme involved in cell cycle regulation.

TeLo is not a well - known term in the context of immortal cell lines.

Answer:

HeLa
