What term describes the type of cells central to research cloning from embryos?

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

Answer: (A)

Stem cells are undifferentiated cells with the ability to self-renew and differentiate into multiple cell types. In cloning research that starts from embryos, embryonic stem cells provide a pluripotent source that can form many tissues, making them central to studying development and potential regenerative therapies. Their broad developmental potential is what makes them the focus for embryo-based cloning research. In contrast, blood, nerve, and skin cells are already specialized and don’t have the same capacity to become a wide range of other cell types, so they aren’t the primary type discussed in this context.
