LINE1 (also L1 and LINE-1) is a family of related class I transposable elements in the DNA of some organisms, classified with the long interspersed nuclear elements (LINEs). L1 transposons comprise approximately 17% of the human genome. The majority of these are inactive, though about 80–100 have retained the ability to retrotranspose, with considerable variation between individuals. T… Nettet18. mai 2024 · Transposable elements (TEs) widely contribute to the evolution of genomes allowing genomic innovations, generating germinal and somatic heterogeneity, and giving birth to long non-coding RNAs (lncRNAs).
