I was asked by a student for a good source for an image of their protein. The most authoritative source for an image is the RCSB Protein Data Bank. As an example I input HLA-DQB1 and selected the first link for Homo sapiens. This data bank will have the images for proteins from any species that have had research done on their version of the protein. Here are some screenshots:
This is another image found by a simple Google search from this site: https://www.researchgate.net/figure/Figure-3-Identical-by-state-SNPs-affecting-HLA-DQB1-binding-groove-The-three_fig1_301588887. As you can see this is from a primary research paper and in this image HLA-DQB1 is being affected by SNPs (single nucleotide polymorphisms).
Any one, or all of these images could be submitted. The point to this question in your task is so you get a sense of what your gene product (protein) actually looks like. You can see mine is made of mostly beta sheets with a couple alpha helices. You only have to submit one, but a few from different angles would be good if possible.

Format: multiple choice, diagrams, problem-solving/analysis, explanations
This test will be made of multiple choice, a diagram section, and problem-solving/analysis questions but not a long answer section.
- replication – p. 222 in your textbook as well as the notes we took
- PCR – purpose, ingredients, how it works (go through three cycles)
- central dogma in general – DNA to RNA to Protein
- mutations – types and how to analyze if they are harmful, definitely harmful, or maybe harmful
- gel electrophoresis – how this works in general and how to analyze a gel
- recombinant DNA techniques – plasmids (what are the necessary components), genes of interest, restriction endonucleases; basically, what are the ingredients and steps required to make a recombinant plasmid
- transcription in detail
- mRNA processing – in detail – 5’methyl-G capping and 3′ Poly A tailing processes
- splicing – removal of introns and the pasting of exons
- translation – from mRNA to proteins in detail
- Sanger vs cycle sequencing – what are the ingredients, how do these techniques work, how to read the data they output
Go here. Click on “Techniques”, then “Sorting & Sequencing”.
Click on “Early DNA Sequencing” and watch this animation.
Click on “Cycle Sequencing” and watch this animation.
Tomorrow we will be doing a hands-on activity that models Cycle Sequencing.
On Wednesday we will be doing an in-class multiple choice/true-false/fill in the blanks activity that counts to your Application category of learning based on these animations.
Here’s a semi-completed one from the example we did in class (HLA-DQB1).
