RNA, a molecule of life, so versatile and bold,
A single-stranded cousin of DNA, with stories untold
A key player in gene expression, a cellular guide,
From transcription to translation, it's a molecular ride
mRNA, the messenger, carries the code,
Transcribing DNA,it hits the road
Carrying instructions, a genetic script,
To the ribosome, where proteins are equipped
rRNA, the ribosomal, a structural component,
In the ribosome, it's always present
Along with proteins, in a complex dance,
Creating the ribosome, a molecular trance
tRNA, the transfer, brings amino acids,
Matching codons, with anticodons, in a precise abyss
Delivering the building blocks, with care and grace,
To the ribosome, the protein-making place
snRNA, the small nuclear, a splicing pro,
Removing introns, a precise flow
In pre-mRNA, it plays its part,
Creating mature mRNA, a work of art
miRNA, the micro, a gene silencer,
Binding to mRNA, a cellular enhancer
Regulating gene expression, with finesse,
Controlling protein levels, a molecular chess
RNA, so versatile, with functions galore,
A key player in cellular life, forevermore
From transcription to translation, and beyond,
RNA, a versatile molecule, ever profound
So, cherish the RNA, the versatile molecule,
A key player in cellular life, a cellular jewel
From gene expression to regulation, it plays its role,
RNA, a fascinating molecule, with a story to unfold.
