Phage $\lambda$integrates into the E. coli genome using site-specific recombination between a phage sequence, identified as attP, and a bacterial sequence, identified as attB. The attP and attB sequences are different sizes: The attP site is approximately 240-bp long, while attB is significantly shorter at approximately 25 bp. Why does it make sense that the attB site is smaller than the attP site?
