Protein Synthesis

Explore Gene Expression from DNA to ProteinThe Protein Synthesis Molecular Model Set from Mega Molecules offers a dynamic, hands-on approach to learning the full process of gene expression. Students explore how information flows from DNA to protein by physically modeling each molecular step, transcription and translation, with precise, color-coded components that bring molecular biology to life. Build DNA and Transcribe mRNALearners begin by constructing DNA nucleotides using phosphoric acid, deoxyribose, and the four nitrogenous bases: adenine, thymine, cytosine, and guanine. These are assembled into a gene sequence (e.g., T–A–C–C–T–G–C–A–G–A–C–T). Next, students transcribe mRNA by pairing RNA bases to the DNA strand, demonstrating accurate base-pairing rules such as A–U and C–G. Model tRNA and Translate ProteinsStudents construct tRNA molecules with built-in anticodons and specific amino acid attachments. These tRNA units match up with mRNA codons, illustrating how tRNA ensures preci
