DNA transposons, also known as "jumping genes," are segments of DNA that can move from one location to another within a genome. They can insert themselves into different parts of the DNA, which can lead to genetic variation and influence gene expression. This mobility is facilitated by specific enzymes that cut and paste the transposons. These elements play a significant role in evolution and genetic diversity. By altering the genetic makeup of organisms, DNA transposons can contribute to adaptation and the development of new traits. Their study helps scientists understand genetic mechanisms and the complexities of genomes.
