[Distribution of pyrimidine sequences of different length and base composition in bacteriophage T5 DNA].
Distribution of pyrimidine tracts of different length (isopliths) with general formula PynPn+1 in bacteriophage T5 DNA was studied. The first seven isoplith fractions were subfractionated by the chain length and the quantity of the resulting non-isomeric oligonucleotides was determined. The pattern of distribution of pyrimidine tracts of various length and base composition in bacteriophage T5 DNA is different from that previously observed in the DNAs of bacteriophages T3 and T7. The observed differences in distribution of pyrimidine nucleotides are in accordance with the other peculiarities of bacteriophage T5 genome.
