no class – Thanksgiving Break
Also remember there are two, short writing assignments, each worth 20 points.
Pick any topic in developmental biology (except your term paper topic) and learn more about it. Then
write a two page paper and include all the sources you used (those can include any sources including web
sites, newspapers, TV, etc). These are due anytime.

Determined (committed)
Differentiate = the cell becomes the final cell type
differentiation is irreversible

“master regulators” like MyoD are transcription factors that
can cause cells to become determined when the gene is expressed.
