Which technique harvests stem cells from human embryos? A. gene cloning B. amniocentesis C. karyotype testing D. therapeutic cloning

Answer: Option B

Explanation: The amniotic stem cells can be taken out from the embryo by the procedure known as amniocentesis. Amniotic stem cells can be defined as the mixture of cells (stem cells) that are present in the amniotic fluid or amniotic membrane.
