CG suppression
From Wikipedia, the free encyclopedia
CG suppression is a term for the phenomenon that CG dinucleotides are very uncommon in most portions of vertebrate genomes. In human and mouse, CGs are the least frequent dinucleotide, making up less than 1% of all dinucleotides. GCs are the second most infrequent, making up more than 4% of all dinucleotides, so CGs are more than fourfold less frequent than all other dinucleotides.
