In recent times, it has been shown that adult cells can be induced to become embryonic stem cells also
called "induced pluripotent stem cells" (iPS). To make this conversion, what has been done to the adult
cells?
a- cytoplasm from embryonic stem cells is injected into the adult cells.
b- The nucleus of an embryonic stem cell is used to replace the nucleus of an adult cell.
C- The adult cells must be fused with embryonic stem cells.
d- New genes are added to the adult cell to convert it to an embryonic stem cell.

"1. it should be, it has been for about 20 years, and it's really not much different in the end than breeding animals to have particular traits. there are always concerns about genetically engineered animals/plants affecting the environment in unexpected negative ways, but i can't think of an example where the fears didn't turn out to be baseless.  

first, as you point out, it would be a great advance in pharmacology, to be able to tailor drugs and their doses to me. the pros involve better medical treatment. the cons involve privacy issues like insurance companies denying coverage to people with genetic risk factors. looking at dna markers wouldn't affect the frequency of genetic diseases, but it would allow detection of them earlier. and ok, actually i suppose that if people used this information to avoid having children with genetic diseases, some might decrease in frequency."

a unit of heredity that is transferred from a parent to offspring and is held to determine some characteristic of the offspring.
