LINEs (Long Interspersed Nuclear Elements)

LINEs, or Long Interspersed Nuclear Elements, are a type of genetic sequence found within our DNA. They are “jumping genes” that can copy and insert themselves into different parts of the genome. Making up a significant portion of human DNA, LINEs are usually inactive but occasionally can disrupt gene function or influence gene behavior. They play a role in genetic diversity and evolution, and their activity has been linked to certain genetic diseases and cancers. Essentially, LINEs are mobile DNA fragments that contribute to the complex and dynamic nature of our genome.
