HETERODUPLEX DNA Meaning and
Definition
-
Heteroduplex DNA is a term used to describe a structure of DNA formed when two DNA strands with slightly different sequences are brought together and paired. The term "hetero" signifies the difference in sequence between the two strands, while "duplex" refers to the double-stranded nature of DNA.
In heteroduplex DNA, the two strands come from different but related sources, such as two different DNA molecules or two different alleles of the same gene. As a result, regions of the DNA strands have base pair mismatches, where the nucleotides on the opposite strands do not perfectly complement each other, leading to the formation of loops or bulges. This can occur due to genetic recombination, template switching during replication, or mutation events.
The formation of heteroduplex DNA has important implications in genetic research and analysis. It can be used to study genetic variation, as the differences in sequence between the two strands can be examined and compared. Furthermore, heteroduplex DNA can serve as a substrate for repair mechanisms that correct the mismatched base pairs, playing a role in maintaining DNA integrity.
Heteroduplex DNA is also relevant in the field of molecular biology as it is utilized in certain techniques like heteroduplex analysis or hybridization methods to identify genetic variations or mutations within specific gene regions. These techniques involve denaturation and reannealing of DNA strands to create heteroduplex DNA, followed by the detection and analysis of mismatches using different methods.

Etymology of HETERODUPLEX DNA
The word "heteroduplex" is formed by combining two root words: "hetero" and "duplex".
1. Hetero: The root "hetero" derives from the Greek word "heteros", meaning "different" or "other".
2. Duplex: The root "duplex" comes from the Latin term "duplex", which translates to "double" or "twofold".
When combined, "heteroduplex" refers to a structure composed of two different DNA molecules or strands. It describes a condition where two DNA strands from different sources (for example, two different individuals) form a double helix structure that contains both matching and mismatched base pairs.
