We have investigated the frequencies of 3 restriction fragment length polymorphisms (RFLPs) of the apolipoprotein B (apo B) gene in normo- and hyperlipidaemic individuals. In individuals with type III hyperlipidaemia, the allele frequency for the RFLP detected with XbaI was significantly different from the allele frequency in normolipidaemic individuals and… (More)
We have used four independently isolated cDNA probes for human apolipoprotein B (apo B), to isolate overlapping genomic recombinants for the 3' portion of the apo B gene. The cDNA clones and a unique fragment from the genomic recombinant have been used to identify the human apo B gene in DNA from a series of rodent X human somatic cell hybrids. Our results… (More)
Two independent methods are used to evaluate the protein-coding information content in different classes of DNA sequences. The first method allows to evaluate the statistical relevance of finding unidentified reading frames, longer than 100 codons, on both DNA strands of: a) 117 DNA sequences that code for 142 nuclear proteins; b) 39 stable RNA coding… (More)
Computer programs, implemented on an Univac II00/80 computer system, for the identification and characterization of protein coding genes and for the analysis of nucleic acid sequences, are described.
