What determines the shape of a protein.
Molecular workbench a tour of hemoglobin. How does a change in the dna code affect the shape of a protein. Sam teachers guide diffusion osmosis and active transport overview students investigate diffusion osmosis and active transport in order to study the movement of molecules into and out of cells. They explore the way concentration and.
34follow the directions below to complete the activity. 35note that you can use the mouse to grab and rotate the hemoglobin molecule and you can zoom in and out of the view of the molecule by holding down the shift key and dragging the mouse. 36notice there are four subunits and each is shown as a different color in the model.
The molecular workbench is more than a simulation. Learn about our work molecular workbench was awarded the prestigious spore prize learn more computational experiment. A computational experiment is a computer simulation of a real experiment or a thought experiment.
Enjoy the videos and music you love upload original content and share it all with friends family and the world on youtube. Our flow of genetic information kitc will first allow your students to model dna replication using color coded foam nucleotides and a placemat then model rna transcription as they copy one strand of dna into mrna using an rna polymerase and finally model protein synthesistranslation as they decode the mrna into protein on the ribosome placemat. Click on the grey boxes to take a tour of a normal hemoglobin molecule and see the location where the single amino acid substitution occurs in sickle cell anemia.
Can a single amino acid change cause a change in the shape of the folded protein whatistheoriginalaminoacid. A virtual tour consists of a series of scenes set by the author to introduce the fascinating molecular. Do not follow the directions on the molecular workbench page.
