Document Summary
Transposable elements: seq that move in genome and often cause genome and pop themselves in and out of gene, 45% of our genome has them, also known as transposons, most of them have. Flanking direct repeat (purple): constant of each type of te and not part of te not. It is generated through transposition when it gets inserted of the new area of genome. Some of the te of terminal inverted repeat (green): they are complementary and inverted to the genome at the ends. It leaves sticky end and te comes into the ends and ligase fills the gap with complementary seq. That"s ho(cid:449) they a(cid:396)e (cid:396)epeats i(cid:374) the ge(cid:374)o(cid:373)e: two major types of te, 1. Dna transposons: transpose as dna, and move dna to their actions: 2. Transcription and mrna that is being made and is copied back into dan through reverse transcriptase and it popped back into genome and it increases copy numbers: spontaneous mutations : te.
