Restriction sites for tetracycline and ampicillin in E coli plasmid

How to memorise which restriction site in pBR322 is for tetracyclin and which is for ampicillin?

You can remember that the enzymes Pst 1 and Pvu 1 cut at the site conferring ampicillin resistance by the trick - Prashant(Pst) Pavar(Pvu) likes the song Amplifier(You can search it if you want 😅)
You can remember that the enzymes BamH1 and Sal1 cut at the site conferring tetracycline resistance by the trick - BTS (BamH1 Tetracyline Sal1)

Comment whether or not you found these methods helpful.
Cheers!
