To help people understand what SARS-CoV-2 actually is, I am pasting its entire genetic sequence below. This is something I worked on yesterday. To understand how the PCR test works, take a look at the sequence below. The PCR process takes a nucleotide sequence “primer” about 20 characters long and creates about a trillion copies of it (thru 40 cycles). If you have even ONE little fragment of RNA matching this 20-character sequence in your sample, then it will be amplified a trillion times until there is so much of it that it can be easily detected. That is what the coronavirus test is. The entire genome of SARS-CoV-2 is below. I have highlighted one of the primer sequences. Try to find it!
Who chose these 20-character primer sequences? Good question.
Any sequence below can be searched in the government NCBI database for nucleotide sequences. Give it a try here! Any random sequence of a length up to 18-20 characters can be randomly found in all kinds of bacteria, fungi, and living creatures.
