Hi everyone! A friend of mine, Doug Halverson, has cloned several pieces of human DNA and has found that they don't all have Alu sequences in them. His question is, in human genes that have been mapped or sequenced so far, have stretches of DNA as long as 10 to 20 kb been found to be Alu free? One way to answer this is to ask how many Alu sequences are in the genome. According to Darnell (J. Darnell and H. Lodish and D. Baltimore", title = "Molecular Cell Biology", year = "1986", publisher = "Scientific American Books, Inc.", address = "N. Y."}) there are 5x10^5 per genome. Since the genome is around 3x10^9 bp, one would expect about 1 every 10kb, but this is guess work. Does anyone know more about the distribution?
