text: Yo, check it out, let me break it down for ya,
  The DNA mismatch repair, it's crucial, no doubt,
  The pathway that removes errors when replication's done,
  MutS, the primary sensor, we're on the run.
  
  Forming an asymmetric dimer, encircling the DNA,
  Bend it and scan for mismatches, that's the way,
  But how does DNA enter the central tunnel, we didn't know,
  The force to bend it, unclear, we had to show.
  
  Listen up, in the absence of DNA, MutS reveals,
  A symmetric dimer, a gap between monomers, it feels,
  DNA enters through that space, no need to fret,
  50 Å of movement, Bm and Am connect.
  
  N-terminal domains press onto DNA, they bend,
  Toroid formation, force from Bm's movement, my friend,
  MutS dimer acts like a pair of pliers, so tight,
  Bending that DNA, it's a sight.
  
  Now let's talk about ATP, it's gotta be expelled,
  Allosteric mechanism, that's what we unveiled,
  When Am binds to DNA, ATP's gotta go,
  This study's got the insight, now you know.
  
  So there you have it, the assembly's clear,
  MutS-DNA complex, the primary event we revere,
  Mechanistic insight, we've brought it to the light,
  In MMR, this study shines oh-so-bright.
