1. DNA duplex
The double-stranded DNA molecule, which has a double helix (usually "right-handed") structure.

2. DNA melting (duplex melting)
Denaturation of a DNA molecule with heat. The double-stranded molecule breaks up into two single-stranded molecules as a result of heat.

3. Double-stranded complimentary DNA (dscDNA)
A duplex DNA molecule copied from a copy DNA template .

4. Exonuclease III
An exonuclease enzyme which removes nucleotide s one at a time from the 5'-end of duplex DNA which does not have a phosphorylated 3'-end.

5. Exonuclease lambda
An exonuclease enzyme that removes nucleotide s from the 5' end of duplex DNA which have 5'-phosphate groups attached to them.

6. Fast component
A segment of eukaryotic DNA consisting of highly-repeated nucleotide sequences which, when the entire duplex DNA molecule is denatured (the double-stranded helix comes apart and becomes single strands) and then allowed to renature (the complementary single strands come together to form a helix), will be the first segment to renature.

7. Hemimethylated DNA
duplex DNA where only one of the two strands are methylated (have -CH3 groups attached to it; this is important for regulating and protecting DNA).

8. Heteroduplex
A double-stranded DNA molecule or DNA- RNA hybrid , where each strand is of a different origin.

9. Heteroduplex DNA
This is DNA that contains complementary strands from two different DNA molecules with similar sequence s.

10. Heteroduplex mapping
Heteroduplex mapping is a lab technique used to locate a particular sequence of nucleotide s. It involves making a heteroduplex by pairing the unknown nucleic acid strand with a reference strand which has a known sequence.
