Research cloning concentrates on creating embryonic __ __ lines from cloned human embryos.

• A. Stem Cell
• B. Blood Cells
• C. Nerve Cells
• D. Skin Cells

Answer: (A)

Cloning research aims to produce embryonic stem cell lines because these cells are pluripotent and can give rise to many different cell types. Embryonic stem cells come from the early embryo and can be grown in culture to form renewable, genetically consistent lines. This versatility makes them especially valuable for studying development, modeling diseases, testing drugs, and exploring potential therapies that require tissues derived from stem cells. In contrast, blood cells, nerve cells, and skin cells are already specialized and do not provide the same broad, expandable resource that stem cell lines offer. So the intended completion is embryonic stem cell lines.
