Some real talk:
It can be difficult to tell with certainty whether a random virus is engineered or not based purely on the sequence, but when we talk about a specific virus, e.g. SC2, we were 'lucky' that we can tell with high certainty it is a natural virus.
Why?

We were lucky in the sense that coronaviruses evolve through recombination (not only random mutations & selection).
That means their genomes consist of a patchwork of puzzle pieces assembled by crossings paths with other CoVs.
In SC2's case, we talking like 27 recombination pc

Each piece comes with its own evolutionary history and can be mapped on a #phylogenetic family tree based on common ancestors & cousin viruses.
This allows researchers to figure out what "crossing events" lead to SC2 genome by sampling CoVs in the wild

🧵#Bioinformatics and its impact on #healthcare, a THREAD🧵🧵:
#Bioinformatics is the application of #computational techniques to the analysis of #biological data, such as #DNA sequences and #protein #structures.
In #healthcare, #bioinformatics is used to gain insights into the #genetic basis of diseases, and to develop new #diagnostic tests and #treatments.
Are you interested in getting started in #bioinformatics but not sure where to begin? Here are some tips to help you get started on your journey. A THREAD🧵🧵:
Start by learning a high-level #programming language, such as #Python or #R, and familiarizing yourself with data structures and #algorithms commonly used in #bioinformatics. The #BioPython and #Bioconductor libraries are great resources for this.
🧬🧵here is a Twitter thread explaining #Bioinformatics in simple terms:🧬🧵
#Bioinformatics is the field that uses computational tools and methods to analyze and interpret #biological #data.
This can include analyzing #DNA and #protein #sequences, predicting the structure and function of #molecules, and modeling biological systems.

#OneYearAgo a "coronavirus #genome from a case of a respiratory disease from the #Wuhan outbreak" was published on #GenBank... 🧐#SARSCoV2
#OneYearAgo "The cluster of infections had raised fears of a potential epidemic after China said last week that the virus causing it was a previously unknown type but came from the same family of viruses that caused the #SARS and #MERS epidemics".🧐
