Henrietta Lacks' cells are considered immortal. Why might this be so?

Cause of death: Cervical cancer

Explanation:

Lacks's cells were the first to be observed that could be divided multiple times without dying, which is why they became known as "immortal". After Lacks's death, Gey had Mary Kubicek, his lab assistant, take further HeLa samples while Henrietta's body was at Johns Hopkins' autopsy facility.

ans.

dna fingerprinting is defined as a process that determines the dna characteristics of an individual. these dna characteristics are unique among individuals as their fingerprints, so it is known as dna fingerprinting.

steps of dna fingerprinting includes extraction of dna from sample, amplification of dna, restriction digestion of amplified dna, and then analysis of dna by gel electrophoresis, respectively.

thus, the next step performed by the scientist is 'to cut the amplified dna (obtained by polymerase chain reaction) by restriction enzymes that cleave the dna into fragments and their analysis.'
