DNA types – Distinction between two types of DNA

DNA types – Distinction is made between two types of DNA:

  • Nuclear DNA, in the nucleus of each cell of the human body consists of 20-25 thousand. genes. After the death of its host quickly degrades.
  • Mitochondrial DNA (mtDNA), contains only 37 genes. During the study, scientists use mtDNA, which is inherited only from the mother, it retains a relatively high resistance to the influence of sexual selection, however, it is a frequent mutations.
