not-yet-known not-yet-known not-yet-known unknown Our knowledge of coronaviruses has grown since their discovery in the 1960s. Back then, scientists found the first one in lab-grown trachea cells from an adult suffering from common cold, and named them as coronavirus for their crown-like spikes; recognising them as a new virus family. Research soon revealed a world of coronaviruses infecting not only humans, but also a menagerie of animals. In our study, we have taken whole genome sequences of 30 coronavirus variants for identifying unique simple sequence repeats (SSRs) and have considered them as biomarkers. Furthermore, we have compared the length of their genome sequences, which reveal insertions or deletions that may be responsible for functioning of the viruses. Additionally, we have analysed the GC content (%), which provide information about replication processes of the viruses, and have studied their relative abundance and density for understanding the prevalence of repeats in the genomic loci. Finally, we have conducted a phylogenetic analysis which explains how these variants are related and potentially how they emerged. With all the analysed data, we can gain deeper insights into the diversity and evolution of coronaviruses that can be instrumental in developing diagnostics, vaccines, and treatments to combat future outbreaks.
