We finished chapter 7, and the third stop in our road map, on how DNA organization influences protein function. We discussed the most common structural motifs of DNA binding proteins and agents that may denature or even degrade proteins.
We also started chapter 9, on regulation of gene expression in prokaryotes. We discussed the basics of positive and negative regulation and the differences in frequency of gene regulation events at transcription, translation and in between.

The PCR song
The highlight of the day was, with no doubt, the performance of The PCR Song by students in this class. You can see the video of the original song by clicking here, or accessing the previous entry in this blog.
The exercise, meant to reinforce the reagents and steps of PCR, ended up being delightful and enjoyable one, even leading to the suggestion to use more songs that summarize processes (a molecular biology greatest hits CD?).
I am open tu suggestions and new ideas!
