THE USE OF AN ETHIDIUM ANALOGUE IN THE DYE-BUOYANT DENSITY PROCEDURE FOR THE ISOLATION OF CLOSED CIRCULAR DNA: THE VARIATION OF THE SUPERHELIX DENSITY OF MITOCHONDRIAL DNA
Estimation of DNA sequence divergence from comparison of restriction endonuclease digests.
An estimation of the DNA sequence divergence between defined DNA secquences of individuals or species may be made from comparison by gel electrophoresis of restriction endonuclease digests. This analysis is applicable to purified DNA sequence of moderate complexity (1-100 X 10(6) daltons) which have diverged by base substitution of 0.5 to 25% of nucleotides
Isolation and characterization of genomic clones corresponding to the human type II procollagen gene.
A recombinant human DNA library was screened using probes corresponding to the chick alpha 1 (II) procollagen gene. This resulted in the isolation of 2 different genomic clones, LgHCol(II)a and LgHCol(II)b. LgHCol(II)a was identified as corresponding to the alpha 1(II) gene by comparative hybridization and DNA sequence analysis. DNA sequence established that LgHCol(II)a extends at least from amino acid 694 of the triple helix through 54 amino acids of the COOH-propeptide. Hybridization with a probe containing only the exon at the 3' end of the chicken gene suggests that the clone contains the 3' end of the human gene. Thus LgHCol(II)a contains approximately 40% of the coding sequences of the human type II collagen gene
