Isolation and characterization of dna
Abstract two contrasting genome-specific dna sequences were isolated from aegilops speltoides (wild goat grass) and hordeum chilense (wild barley), each representing more than 1 % of the genomes these repetitive dna fragments were identified as being genome-specific before cloning by genomic southern hybridization (using total genomic dna as a probe), and hence extensive screening of clones.
