Description
Explore Gene Expression from DNA to Protein
The 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 mRNA
Learners 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 Proteins
Students construct tRNA molecules with built-in anticodons and specific amino acid attachments. These tRNA units match up with mRNA codons, illustrating how tRNA ensures precise amino acid delivery at the ribosome. By linking amino acids with strong bonds, learners assemble a polypeptide chain and witness the formation of proteins from genetic code.
Visualize Mutations and Molecular Impact
The set enables students to simulate point mutations and observe how a single base change can affect protein structure and function. This reinforces the connection between genotype and phenotype, enhancing understanding of molecular genetics and mutation-driven variation.
Instructional Support for All Learning Environments
An included guide walks learners step-by-step through the entire process, complete with diagrams, codon charts, and analysis activities. Ideal for high school biology, introductory college courses, and homeschool settings, this model set transforms abstract molecular concepts into clear, interactive lessons that deepen comprehension and spark curiosity.
