Atelier 5 - Coronavirus and proteins...
Publication (coming soon)
Since December 2019, a new coronavirus of animal origin started to infect humans: this is the beginning of a pandemic
This virus is called Severe Acute Respiratory Syndrome-related Coronavirus 2 (SARS-CoV-2).
He is responsible for the disease called Coronavirus disease-19 (COVID-19).
These activities highlight how bioinformatics can be harnessed to study a new virus, its genomes, its proteins, its origin...and its evolution !
"We are learning so much, so fast!" E. Hodcroft
Objectives
- Discover SARS-CoV-2 genome(s) and protein(s)
- Compare SARS-CoV-2 genomes sequenced in various countries: look for the differences (mutations) and identify the virus variants
- Discover how to monitor the impact of a mutation such as the N501Y mutation on infectivity and immune response
- Discover bioinformatic databases - GenBank (DNA), UniProtKB (protein), PDB (3D structure), Viralzone
- Discover bioinformatic tools (Blast, BLAT, align, translate)
- Better understand current research... and the challenges faced!
- DNA (genome) and proteins
- Video: from DNA to protein
