In bioinformatics, BLAST is an algorithm and program for comparing primary biological sequence information, such as the amino-acid sequences of proteins or the nucleotides of DNA and/or RNA sequences.

Basic Local Alignment Search Tool

BLAST finds regions of similarity between biological sequences. The program compares nucleotide or protein sequences to sequence databases and calculates the statistical significance. 1)

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.

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.

How to BLAST your way to the truth about the origins of COVID-19

Using BLAST is easy. I'm going to show you how easy and how to prove that SARS-Cov-2 is man-made Dr Ah Kahn Syed - Dec 28, 2021 2)

Absolute proof: The Gp-120 sequences prove beyond all doubt that "COVID-19" was man-made

The “missing link” was there in Pradhan's paper all along, we just needed to ask the right question: “where are the genome sequences for the Gp-120 inserts” Substack - Arkmedic's blog - Dr Ah Kahn Syed - April 10, 2022

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:3)
