Description: Overlapping genes are those that share some of the same nucleotide sequences, meaning they can overlap in the genome. This phenomenon occurs when two or more genes are located in the same region of DNA but are expressed differently, potentially resulting in the production of distinct proteins or RNA products. Gene overlap can be total or partial and can occur in different orientations, meaning one gene may be on the forward strand while another is on the complementary strand. This type of genetic organization is an example of the complexity of the genome and how nature has optimized the use of genetic space. The existence of overlapping genes raises interesting questions about genetic regulation, evolution, and gene functionality, as their interaction can influence gene expression and protein production. Additionally, overlapping genes are an area of interest in bioinformatics, where computational tools are used to analyze and predict the functions of these genes in different organisms. Their study is fundamental for better understanding molecular biology and genetics, as well as for the development of new therapies and treatments in medicine.
