ABCs of AGCT

Apes access amino acids along alternative animal avenues

Beget brutally boorish brews

Considering choices chemistry can choose,

Defying deletions, determinantly diffuse.

.

Engendering everything's essential epigenetics

From faulty flora fructose for functional fauna frenetics

Gathering glucose, garnering genetic gloom

How heroic histology has helically hewn!

.

Into inky instants invoking insidious institutions opportune

Just jetsam jokes, joining joculations, jejune,

Keeping kleptomanic ketones,

Laughing, lending life liliputian lysosomes.

.

Meiotic'ly, mitotic'ly mix'd messily

Neanderthal napthenes, neverthelessily;

Open opacities of other opaque openings

Purposely promoting primitive promotions

.

Quietly, quaint quotes quickly quiescing,

Refusing ribonucleic retrograde recessing;

Securing somatic secrets sent spiritually

Toward the terrible tier turnover, toppling tearfully.

.

Uselessly upsetting, unsettled, undertuned,

Variations vetting viability's vicissitudes;

With weathered wherewithal withering warm

Xeric xenogenesis xeroxes X's xenofarm.

.

Y's, yes, yearn, yet yielding

Zoological zenithed zillions.

Now I've evolved my ABCs

Tell me which — survive — species.
