Transposons and Mechanisms of Transposition Wuda Wang(MCB720)

Transposable Elements Transposons -1. The Discovery of Transposable Element -2. Two types of transposons 2.1 Insertion Sequence (IS) 2.2 Composite Transposon -3. Two mechanisms of Transposition 3.1 Replicative Transposition 3.2 Non-replicative Transposition Retrotransposons

1. The Discovery of Transposable Element

2.1 Insertion Sequence (IS)

Formation of target repeats

2.2 Composite Transposon

3.1 Replicative Transposition

3.2 Non-replicative Transposition Mechanism 1: share some steps with replicative transposition

Mechanism 2: cleavage and ligation
