Lyrics:
Verse 1
Neon microscopes, a midnight glow
Young cells running like a high-speed show
But in the strands, little knots appear
And every mile gets steeper here
Pre-Chorus
When BRCA2 lets go, the lanes turn tight
Forks slow down in the white-hot light
A twist, a pause, a crack in the track
And the map can’t take it back
Chorus
G-quadruplex, knot in the code
Stress on the line where the young cells rode
If you can’t repair what the spirals do
You bleed your future in ones and twos
But there’s a grip in the chaos—see it flex
Find the weak link at the G-quadruplex
Verse 2
Breakpoints singing where the G4s lie
Scars that glitter when the genomes try
Stabilize the knot, and the wheels shake hard
Fragile engines in a graveyard yard
Bridge
Then PIF1 rises like a roadside flare
Unwinding danger out of thin air
Take that helper and the darkness grows
Micronuclei like falling snow
So hold the knot, or cut the thread
And choose what lives when the cells misread
Final Chorus
G-quadruplex, knot in the code
Stress on the line where the young cells rode
BRCA2 gone, the sparks break through
But the rescue has a cost we can pursue
Turn the helix to reveal what’s next
Aim at the lifeline—PIF1 at G-quadruplex
