Review mitosis steps
- student each write 5 features of mitosis & interphase (no cytokinesis)
- collect class features, mix
- students make sequence (discard duplicates; add what is missing)
- students do this by phase (just record steps/ features in text by phase to begin)
|
Students answer "2.5 Writing to learn" questions on paper by hand

Use HHMI article of protein coat variability in pathogenic mircrobes.
- Discuss significance of art piece (before reading or describing article). Valuable discussion of symbolism; connect visual thinking to science thinking.
- Relate content to membranes; possibly:
- structure and role of membrane proteins in identifying cells (t-cells, antigen presenting cells, plasma cells, etc)
- antibody and antigen specificity
- variability in glycoprotein structure (in article in microbes)
- variability in genes controlling Ab production (may include "jumping" or transposable genes.
