Question

Why are immortal cell lines important for biological research?

Answer 1

The correct answer is B. “They can replicate indefinitely and do not experience natural cell death.”

Answer 2

Ans.

Immortal cell lines show a population of cells, derived from a normal cell of a multicellular organism that would generally not divide indefinitely, but due to genetic mutations, have evaded normal cell death or cellular senescence and become immortal.

These cells are important for biological research as they can replicate indefinitely and provide a continuous supply of desired materials, and they are easy to use and cost effective.

Thus, the correct answer is option b). they can replicate indefinitely and do not experience natural cell death.
