RNA Transcription & Splicing Processing
Walk through the Central Dogma. Bind RNA Polymerase II to the promoter, elongate the pre-mRNA transcript, and execute post-transcriptional modifications including 5' Capping, Poly-A tailing, and spliceosome intron cleavage.
AP BIOLOGY
Ribosome Translation Simulator
Step through translation: Small/Large ribosomal subunit assembly, A/P/E site tRNA translocation, peptide bond formation, and termination at a STOP codon.

Operon Regulation (Lac vs Trp)
Compare Inducible (Lac) vs Repressible (Trp) bacterial operons. Toggle inducer/corepressor presence to observe immediate repressor conformational changes and RNAP blockage.
AP BIOLOGY
Epigenetic Regulation
Visualize how DNA Methylation tightly coils chromatin (turning genes OFF) and Histone Acetylation loosens chromatin (turning genes ON), bypassing the underlying DNA sequence.
