[Pandas 2](https://colab.research.google.com/github/nekrut/BMMB554/blob/master/2021/ipynb/Pandas2.ipynb) - data wrangling with SARS-CoV-2 data.

## Journal club every Thursday

1. I will distribute list of journals as a part of the homework.
1. Pick one.
1. Before next Thursday select 1 (one) paper that you find interesting.
1. Summarize it with one slide for 1 min. Just the take home message!

Example -> [Comprehensive mapping of mutations to the SARS-CoV-2 receptor-binding domain that affect recognition by polyclonal human serum antibodies](http://dx.doi.org/10.1101/2020.12.31.425021)
