Background: The widespread outbreak of SARS-CoV-2 has become a deal threat for human health. This new emerged virus coupled with severe acute respiratory syndrome (SARS) and middle east respiratory syndrome (MERS) viruses belong to coronoviridae family, which develop SARS in human being. However, prior to the emergence of virulent viruses, the coronaviruses were known as the leading causes of mild common cold. Getting more knowledge about the genome organization of different strains can conduct us how these viruses evolve and become a virulent strain. Here, we reported the difference of oligonucleotide distribution contributing in genome of two groups of coronaviruses, SARS related viruses versa common cold coronaviruses, by employing weighting algorithms approaches.
Results: In this study, we found a few oligonucleotides, which significantly distinguish two viral groups. Among dinucleotide’s features, the discrepancy of TC and CC between SARS related viruses and common cold coronaviruses was quite considerable. Furthermore, CC dinucleotide was sequentially repeated in a few multinucleotide patterns including CCA, CCAC, ACCAC, and CACCAC motifs with the highest values, which also discriminated two viral groups.
Conclusions: Theses remarkable oligonucleotides might point towards the existence of some particular RNA elements that might be involved in viral infectivity.
