Statistics of AT- or GC-rich
regions
What is the probability of observing a “run”
of the same nucleotide (e.g., 25 A’s)
 Let px be the mononucleotide probability of
nucleotide x
 The per nucleotide probability of a run of N
consecutive x’s is pxN
 The probability of occurence in a sequence
of length L longer than N is ≈ L pxN

