===== BLAST =====
{{ ::nih_blast_header.png?400|}}
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. ((https://blast.ncbi.nlm.nih.gov/Blast.cgi))

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

==== 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:((https://arkmedic.substack.com/p/absolute-proof-the-gp-120-sequences))
