BLAST is the NCBI/NIH (aka US government) repository for genomic and proteomic sequences, amongst other things. It is where all genome scientists around the world deposit their sequences if they make a discovery. Its main function is to allow comparison of gene sequences and discovery of sequences that match one that you might have come across in your experiment. | BLAST is the NCBI/NIH (aka US government) repository for genomic and proteomic sequences, amongst other things.

- | What’s a gene sequence? It’s a line of code, made up of any combination of 4 letters in a sequence. BLAST has two sections - nucleotide (BLASTn) and protein (BLASTp). BLASTp deals with amino acid sequences, in just the same way as nucleotide sequences. ((https:// | + | What’s a gene sequence?

+ | Following on from December’s article “How to BLAST your way to the truth about the origins of COVID-19” where I explained how the four “inserts” described in Pradhan’s Feb 2020 paper showed definitively that the SARS-CoV-2 genome had to have been man-made, there has been considerable interest and a lot of push-back from those whose reputations are on the line. | ||
+ | |||
+ | Until now we have only discussed the peptide (i.e. amino acid) construction of the 4 sequences referenced in Pradhan’s paper that showed that the main differences between the spike protein of SARS-CoV-2 and any other previous coronavirus known were contained in these “Inserts”. Here they are: | ||
