Open the book nearest to you and post from page 56 the 5th sentence and 2 to 5 sentences thereafter:
"All women who give a family history of boys with developmental delay, extreme hyperactivity, and speech and language problems should be offered fragile X carrier testing. All DNA tests require recovery of DNA; this is accomplished by obtaining nucleated cells. For DNA analysis of newborns, children, or adults, nucleated cells are easily recoverable from peripheral blood samples."~Obstectrics and Gynecology 4th ed. Beckmann et al; Lippincott.
Tells you what sort of books I have around me! :) Now go to mass, its a holy day of obligation!
