With respect to double-strand break repair, heteroduplex DNA ______________ . Select the THREE that apply. Select the THREE that apply. always shows complete complementarity can be formed when broken DNA strands invade non-sister chromatids is double stranded contains DNA strands that originate from the broken and the unbroken DNA duplex

Respuesta :

Heteroduplex DNA

Explanation:

With respect to double strand break repair, heteroduplex DNA can be formed when broken strands invade non sister chromatids

  • Heteroduplex DNA is formed during homologous genetic recombination
  • Holliday junction is formed during the break model of homologous recombination by break in DNA and strand invasion,each invading strand joins to the broken end of other DNA molecule,creating a Holliday junction
  • Two types of cleavage occurs in this type of junction-horizontal and vertical cleavage
  • Cleavage in vertical plane produces cross over recombinant consisting of 2 heteroduplex DNA
