My favorite DNA blog is Eye on DNA.
Dr. Hsien-Hsien Lei's latest posting is "100 Facts About DNA."
While it may be more than you need right now, it provides information that you might have wanted to look for, but didn't know where or how.
In addition to scientific information about DNA - provided in short, easy snippets - it offers other interesting factoids:
Did you know that if you unwrap all the DNA you have in all your cells, you could reach the moon 6,000 times?
It would take a person typing 60 words per minute, eight hours a day, around 50 years to type the human genome.
If all three billion letters in the human genome were stacked one millimeter apart, they would reach a height 7,000 times the height of the Empire State Building.
