Human identical sequence The human identical sequence (HIS) is a sequence of RNA elements, 24-27 nucleotides in length, that coronavirus genomes share with the human genome .[ 1] In pathogenic progression, HIS acts as a NamiRNA (nuclear activating miRNA) through the NamiRNA-enhancer network to activate neighboring host genes.[ 2] [ 3] The first HIS elements was identified in the SARS-CoV-2 genome, which has five HIS elements; other human coronaviruses have one to five.[ 1] It has been suggested that these sequences can be more generally termed "host identical sequences" since similar correlations have been found between the genome of SARS-CoV-2 and multiple potential hosts (bats , pangolins , ferrets, and cats).[ 1]
