4 hairs, plucked from you head will yield about 1 microgram of DNA. How many micrograms of DNA can be extracted from a SINGLE hair root? [Show your work.] [answer: If 1 microgram of DNA/4 hair roots, then .25 micrograms/root or 1 hair root=.25 micrograms of DNA.] <---[part A] [actual question]---->How many nanograms does this represent?
1 gram=1,000,000 micrograms
1 gram=1,000,000,000 ng [nanograms]
1,000,000 micrograms=1,000,000,000 ng
1 microgram=1000 nanograms
.25 micrograms=250 nanograms
ANSWER: 250 nanograms
