Outline of Final Research Achievements |
Repetitive sequences occupy large fractions of their host genomes, and their organization is thought to undergo considerable changes in evolutionary processes. The purpose of the present study was to reveal actual changes that had occurred in the evolution of hominoids. Main results and their significance were: (1) alpha satellite DNA has been replaced by another repetitive DNA in a gibbon genome, (2) a novel transposon was, and can be in the future, formed and expanded in hominoid genomes, and (3) the evolutionary origin of the higher-order repeat structure of alpha satellite DNA is older than that commonly postulated.
