That makes the 1% of places in the genetic code that account for human variation very interesting…” Momentum Winter 2006-2007, DNA Rubic “Some geneticists have calculated the differences in human and chimpanzee DNA as just over 1%, some at 1.6%, and others at 1.8%.” Momentum Winter 2006-2007, What we learn from Chimpanzees

Cell types The human embryonic stem cells cultured have been observed to randomly differentiate in culture into a variety of different cell types, including (A) gut, (B) neural cells, (C) bone marrow cells, (D) cartilage, (E) muscle and (F) kidney cells. www.news.wisc.edu/packages/ stemcells/3327.html

They are all the same cells – They all have the same genetic material, The only difference is what is turned on and what is silent.

How do we measure it? presence, concentration, activation state, etc. of specific biological molecules. How do we measure the variations?
