Low repetitive sequences


 * classic genes
 * some occur in a single specimen in genome
 * a unique and irreplaceable sequence with very specific and unmistakable information content
 * others occur in a larger copy number (tandem rows, e.g. genes for rRNA = rDNA (400 per genome))
 * similar, but non-identical genes form a gene family, they usually have a common origin + occurrence in groups
 * orphon – a member of the genetic family located separately
