Pyodide: Python code boxes, with the HBB coding sequence

Edit the code and press Run, or Ctrl+Enter. Python runs in your browser, in the background. It downloads (about 6 MB) when you first click in a box, and box 4 fetches Biopython and matplotlib. The boxes share one Python session, so run them in order.

1. The HBB coding sequence: length and GC content

2. Reverse complement and translation, by hand

3. The sickle-cell variant, c.20A>T. Then try c.19G>A (HbC) or c.79G>A (HbE).

4. Packages: Biopython checks your translation, and matplotlib draws a chart
