Hybridoma cells enable continuous monoclonal antibody production

Steps:

• Identify mouse cancer cells (myeloma): Divide continuously but do not produce specific antibodies.
• Identify B-lymphocytes: Produce antibodies but have limited division capacity.
• Identify hybridoma cells: Fusion of myeloma and B-lymphocytes, combining continuous division with antibody production.
• Select row where only hybridomas are marked ✓ for both traits.

Why C is correct:

• Hybridoma cells, per hybridoma technology definition, fuse B-lymphocytes with myeloma cells to achieve immortality and monoclonal antibody secretion.

Why the others are wrong:

• A: Incorrectly marks B-lymphocytes ✓, which do not divide continuously.
• B: Incorrectly marks mouse cancer cells ✓, which are not directly involved in antibody production.
• D: Incorrectly marks B-lymphocytes ✓, which lack continuous division.

Final answer: C
