title: Sequence organization of porcine DNA.
abstract: The sequence organization of porcine DNA isolated from thyroid has been analyzed by hydroxylapatite (HAP) chromatography. The reassociation of 0.4 kilobase (Kb) DNA fragments shows, besides the presence of 5% inverted repeat sequences (foldback DNA), that 45% of the genome is represented by high (10%) and intermediate (35%) repetitive components, whereas the remaining 50% is unique sequences. 30% of the unique sequences consists of 1,000 nucleotide fragments interspersed with repetitive elements 400 nucleotides in length. The remaining 20% is longer unique sequences (10,000 nucleotides) apparently not linked to repetitive elements.
