Biology - June 2007

I just heard on the news that they are now finding they can produce stem cells from skin cells. If the government had just said "Yes, use embryos for your stem cell research" do you think that scientists would be researching more now to find alternatives, like umbilical cords, and now skin?

The usefulness of amniocentesis was limited until the 1960s because:


before then, there was no way to visualize chromosomes

it was too expensive for anyone to afford

ethical concerns prevented the extraction of fetal cells

the correct number of human chromosomes was not determined until the 1950s

before then, it was not known that a fetus sloughed off epidermal cells
