text: Yo, check it out, I got something to say
  'Bout metagenomic DNA, it's the DNA that's on display
  Research topic that's got scientists intrigued
  Uncultivated microorganisms hold the keys
  
  They got genes with potential, biotechnological applications
  We gonna dive deep, no hesitations
  Introducing a novel Si-C-N chromatography approach
  Extracting gDNA from samples, we gonna encroach
  
  Amorphous Si-C-N ceramic, that's the key
  Made from pyrolysis of polycarbosilazane, you see
  Heat it up to 1350 degrees C in Ar
  That's how we get the ceramic, taking it far
  
  Purified gDNA fragments, at least 12 kilo base pairs
  No contaminants, we takin' care
  Ready for restriction enzyme digestion, we got five
  Polymerase chain reaction amplification, we gonna thrive
  
  Detecting phylogenetic groups, native microorganisms in sight
  Using this Si-C-N material, we gonna shine bright
  Pure gDNA, ready for the purification step
  In the molecular biology game, we ain't gonna fret
  
  So remember this Si-C-N technique, it's top-notch
  Making strides in research, ain't gonna stop
  Metagenomic DNA, unlocking the unknown
  With biotechnological potential, we gonna own!
