Question

Finite cell lines are known as

• A. Fresh cell lines
• B. Immortal cell lines
• C. Cell lines which grow through a limited number of cell generation
• D. Secondary cell lines

Hint:

• Finite cell lines Limited divisions, normal cells.
• Immortal cell lines Unlimited divisions (e.g., HeLa cells).

Answer 1

The Correct Option is C

In biotechnology, finite cell lines refer to cell populations that possess a limited number of cell divisions or generations before they cease proliferation. This characteristic distinguishes them from immortal cell lines, which can proliferate indefinitely. 

The correct answer to the question "Finite cell lines are known as" is: Cell lines which grow through a limited number of cell generations

Finite cell lines are typically derived from normal tissue cells and have a defined lifespan following the Hayflick limit, where they undergo senescence after approximately 40 to 60 cell divisions in culture. Therefore, finite cell lines provide a valuable model for studying biological processes during a defined lifespan.
