Overlapping Gene Concept

Overlapping genes are segments of DNA where two or more genes share some of the same DNA sequences but are read in different directions or frames. This means part of the genetic code is used to produce multiple proteins, depending on how it is read. Overlapping genes help maximize the use of limited genetic material within a cell, especially in compact genomes like viruses. They also allow for coordinated regulation of related genes, playing a role in complex biological processes. Essentially, overlapping genes are a clever way nature economizes genetic information and enhances functional diversity.
