  • n. a length of double-stranded DNA containing two thousand nucleotides, one thousand on each strand
  • n. a length of single-stranded RNA containing one thousand nucleotides


formed through affixing the prefix kilo- (one thousand) to the noun base (colloquial for a nucleotide in DNA or RNA) (Wiktionary)


  • Structural variations of DNA greater than 1 kilobase in size account for most bases that vary among human genomes, but are still relatively under-ascertained.
