text: Yo, check it out, here's the deal,
  When a large linking number comes, things get real.
  A circular rod with no curves in sight,
  Straight as can be, stress-free, that's right.
  
  But listen up, 'cause we got more to say,
  Even a rod with a little curve will sway.
  No matter how small that intrinsic bend,
  A twist will make it writhe, my friend.
  
  From the circular shape, it starts to unwind,
  A continuous writhing, you'll surely find.
  The abrupt writhing we see, it's plain to see,
  Only happens when the curve's gone, you feel me?
  
  Now let's talk about DNA, elastic models in play,
  This result has implications, let me convey.
  Circular DNA, it's got its own game,
  Understanding its behavior, ain't that a claim?
  
  So remember this knowledge, let it sink in,
  Large linking number, curves make it spin.
  A rap about science, breaking it down,
  Hope this passage got you, feeling renowned.
