text: Yo, check it, listen up, I got a story to tell,
  'Bout the delta-globin genes, Japanese patients as well.
  Cloned 'em both, normal and homozygous thalassemia,
  Checked the sequence, hold on, I got the media.
  
  Comparin' the nucleotide sequence, let's dissect,
  With pH delta 1, Maniatis et al.'s select.
  Found differences in IVS 2, let me break it down,
  Positions 137, 151, 186, 188, and 291, hold the crown.
  
  Don't forget 292 and 540, one base swaps,
  At 339 and 823, one base additions, non-stop.
  At 548, there's a deletion, it's been erased,
  And a duplication, 9 bp, 651 to 659, perfectly placed.
  
  The 3'-flanking sequence, it's got some changes too,
  At 51 and 98 nucleotides, 3' to AATAAA, it's true.
  But in the region we studied, no differences we see,
  Between the normal subject and the delta-thalassemia.
  
  So these differences might just be polymorphisms, you know,
  In the delta-globin gene, Japanese individuals show.
  Data suggests IVS 2 is more diverse, outshinin' the rest,
  And there might be other DNA regions affectin' the gene's express.
  
  Yeah, that's the scoop, the knowledge I bring,
  Rappin' about genetics, makin' science sing.
  The delta-globin genes got their own rap flow,
  Japanese patients, holdin' it down, let's go!
