130s Classroom → 35s Sub-90 Target27-Q Biology Mock
Archetype Sub-90 Dry-Wipe Invariant (Recombinant DNA: Restriction Endonucleases, Sticky Ends, Ligase & Plasmid Marker Screening): Memorise the 3 recombinant rules: (1) Same restriction enzyme cuts both donor & plasmid -> complementary sticky ends (H-bonds form spontaneously). (2) DNA ligase seals the sugar-phosphate phosphodiester backbone. (3) n cuts in a circular plasmid = n fragments.
