The nucleotide sequence displayed is a 100% match to six SARS-CoV-2 sequences in public databases, all of them originating from the East Coast of the United States. The sequence is from nucleotides 26202-26280 of the virus genome and overlaps an unknown open reading frame/gene named ORF3a. One of the matching sequences is [https://www.ebi.ac.uk/ena/data/view/MT344963]. However, SARS-CoV-2 is an RNA virus, and so its genetic material (not containing any DNA) would not include thymine (T) but would use uracil (U) instead. The sequence uses the codes of DNA as {{w|RNA sequencing}} involves copying the genome into a DNA, and the DNA code is more familiar anyways. | The nucleotide sequence displayed is a 100% match to six SARS-CoV-2 sequences in public databases, all of them originating from the East Coast of the United States.
