A transposable element (TE, transposon, or jumping gene) is a DNA sequence that can change its position within a genome, sometimes creating or reversing mutations and altering the cell's genetic identity and genome size.
Almost 50% of the human genome contains transposable elements. I have several questions:
- how rarely are they changing positions along the genome?
- Are these events most likely to occur during Meiosis, Mitosis? Or they could come in an action in other parts of the cell life cycle?
- Do humans nowadays contains almost the same genetic information (99,9%) including these elements? or does similarity occur only in the protein-coding region?
