Visualising DNA, RNA & Proteins Jalview School Workbook Resources
Visualising DNA, RNA and proteins workbook is aimed at 16-18 year old secondary school students studying Higher, Advanced Higher or A level biology.
The easy-to-use design requires only a desktop or laptop computer with a web browser and internet access.
The workbook contains 4 practical web-based bioinformatic projects:
Project 1 views DNA and RNA sequences and their 3D structures.
Project 2 views protein sequences and their 3D structures.
Project 3 compares the sequence of human myoglobin protein with myoglobin sequences from other animals; then the student views the coding DNA sequence, and codons, alongside the protein.
Project 4 views exons and introns in the human haemoglobin subunit beta (HBB) gene. This is the gene involved in sickle cell anaemia, an inherited red blood cell disorders which affects millions of people throughout the world. The genetic mutations linked to this disease is identified by viewing the coding DNA and its protein product in a split-screen viewer.
(i) Click on the ‘View the School Workbook’ link in Section 1 to open the booklet in an adjacent window, or download the pdf depending on the browser.
(ii) Follow the instructions in the workbook, the links in Section 2 start each exercise by launching JalviewJS and loading the sequences.
If you get stuck, the videos in section (b) may help.

(a) What is Jalview?
Jalview is one of the most widely used applications for visualising and analysing DNA, RNA and protein multiple sequence alignments. It is free-to-use computer software with an interactive multi-window interface. This allows researchers to read files directly from public biological databases and view sequences, 3D structures and evolutionary trees. Jalview has a number of analysis tools for aligning sequences, measuring similarities, exploring features and comparing structures. Jalview has been developed in Prof Geoff Barton's group in School of Life Sciences the University of Dundee, with the funding support of the BBSRC and the Wellcome Trust.
