-
A) The non-stem cells have lost the promoters for more genes. B) The two kinds of cells have virtually identical gene expression patterns in micro arrays C)The non-stem cells have fewer repressed genes D) Adult stem cells have more DNA nucleotides than their counterparts E) The Cells from the two sources exhibit different patterns of DNA methylation. Thanks in advance for the help =D

Answer:
I think the best answer would be E. Promoters are effected by methylation so in a sense A could be correct. B, C, and D are all pretty far off.
