Building Model of DNA, RNA, and Protein Synthesis

 

 

1.1.            Goal

 

f  To study DNA, RNA, and protein synthesis using models

1.4.            Working Procedure

 

Make a three- or two-dimensional model as follows.

 

·        DNA molecular structure

Make a model that shows the double-helix configuration of deoxyribose, phosphate and bases of DNA.

·        DNA replication

Make a short model of DNA (about 10 nucleotides). Then make the replication model.

 

·        mRNA formation

Build the transcription mechanism of DNA into mRNA by determining the DNA template.

·        Control of mRNA on protein synthesis

Build models of amino acids, tRNA, and short chain of mRNA. Show how translation on the base sequence of mRNA into protein is done.

·        Ribosome work

Make two ribosome models. Move them along the chain of mRNA to show translation and its product of polypeptide chain.
