A new approach to the study of nucleotide sequences in DNAs
Laboratoire de Genétlque Moléculaire, Institut de Blologie Moléiculalre Paris 5e, France
Received November 6, 1973. The composition of the 3'terminal, 5'terminal and 5'penultimate nucleotides of the oligonucleotides released by spleen acid DNase and snail acid DNase from five repetitive DNAs (guinea pig, mouse and crab satellite DNAs, yeast mitochondrial DNA and poly (dAT :dAT)) and four eukaryotic DNAs (calf thymus, guinea pig and mouse liver DNAs, and yeast nuclear DNA) have been investigated and found to deviate in characteristic ways from those expected for bacterial DNAs having comparable base compositions. The deviation patterns obtained represent a novel way of characterizing and comparing different DNAs on the basis of the frequency of the nucleotide sequences they contain.
