Question

explain how stem cells are used. What is the difference between therapeutic and reproductive cloning?

Answer 1

Uses of stem cells:

Since stem cells have the ability to turn into various other types of cells, scientists believe that they can be useful for treating and understanding diseases. Stem cells can be used to:

• grow new cells in a laboratory to replace damaged organs or tissues
• correct parts of organs that don’t work properly
• research causes of genetic defects in cells
• research how diseases occur or why certain cells develop into cancer cells
• test new drugs for safety and effectiveness

Difference :

Reproductive cloning involves creating an animal that is genetically identical to a donor animal through somatic cell nuclear transfer. In reproductive cloning, the newly created embryo is placed back into the uterine environment where it can implant and develop. Dolly the sheep is perhaps the most well known example. In therapeutic cloning, an embryo is created in a similar way, but the resulting "cloned" cells remain in a dish in the lab; they are not implanted into a female's uterus.
