Abstract
A high percentage ofDNA sequence noted in higher organisms is highly repetitive in nature. Such sequences may be highly homogeneous, moderate, minor and inverted. Those sequences are found in different loci including introns, spacers, transposons, in addition to their interspersion with unique sequences. Such sequences share the property of amplification, dispersion and possibly mobility. The term ‘DynamicDNA’ has been proposed to account for their varied property. Their presence may account for “C Value Paradox” in eukaryotes. Evolutionary advance is also associated with increase or decrease of repeated sequences.
