RNA-based transposition
RNA-based transposition involves segments of genetic material called transposons, which can move within DNA. In this process, the transposon’s DNA is first transcribed into RNA. This RNA is then reverse-transcribed back into DNA, often facilitated by an enzyme called reverse transcriptase. The new DNA copy integrates into a different location in the genome, allowing the transposon to spread or relocate. This mechanism is common in some viruses and in certain genetic elements within cells, contributing to genetic diversity and evolution by enabling the movement of genetic sequences within the genome.
