Document Summary
Mobile genetic elements: transposable elements (te, they are called transposable elements because of their mode of action/movement. 14. first identiied in corn, but was not fully understood (not until bacteria) 15. have the ability to move- only function is to either replicate or move around. 16. purpose in life is to move and make copies of themselves. 17. genes in the middle are actually responsible for the movement of sequences. 18. does not mean that they are actively moving around all the time. 19. inverted repeat on the end and genes in the middle- genes are responsible for the movement. Transposition may be cut or copy or paste. 20. can move by copy and pastor cut and paste. 21. cut and paste- genetic element excises itself from dna and moves to target site. 1: directly moving themselves from one location to another, here there is a target site for the insertion but this is not always the case.
