Although DNA replication, repair, homologous recombination occur with high fidelity to ensure the genome identity between generations, there are genetic processes that rearrange dNA sequences and thus lead to a more dynamic genome structure

Two classes of genetic recombination for DNA rearrangement: Conservative site-specific recombination (CSSRE recombination between two defined sequence elements Transpositional recombination (Transposition: recombination between specific sequences and nonspecific DNA sites
Two classes of genetic recombination for DNA rearrangement: • Conservative site-specific recombination (CSSR): recombination between two defined sequence elements • Transpositional recombination (Transposition): recombination between specific sequences and nonspecific DNA sites
