A researcher is using adult stem cells and comparing them to other adult cells from the same tissue. Which of the following is a likely finding?
A) The cells from the two sources exhibit different patterns of DNA methylation.
B) Adult stem cells have more DNA nucleotides than their counterparts.
C) The two kinds of cells have virtually identical gene expression patterns in microarrays.
D) The nonstem cells have fewer repressed genes.
E) The nonstem cells have lost the promoters for more genes.

Question

Quizplus · Accepted Answer

Adult stem cells and other adult cells from the same tissue may exhibit different patterns of DNA methylation. DNA methylation patterns can influence gene expression and cellular specialization. Adult stem cells differ from other adult cells in their ability to differentiate and form other cell types, so it is likely that they exhibit different patterns of DNA methylation.
