Abstract:
The coronavirus disease (COVID-19) belongs to the family Severe Acute Respiratory Syndrome (SARS-CoV). It can be more severe for some persons and can lead to pneumonia or breathing difficulties resulting in the death of immune-compromised patients. We performed a phylogenomic and phylogeographic tree from the collected datasets. Phylogenomic analysis or sequence-based phylogeny showed an evolutionary relationship between the geographical strains. The phylogenomic tree grouped into two major clades consists of various isolates of SARS-CoV-2 and Bat SARS-like coronavirus, Bat coronavirus, and Pangolin coronavirus. The phylogenetic neighbor of newly sequenced Indian strains (Accession: MT012098.1, MT050493.1) was revealed to identify the variations between the nCoV-19 strains. The results showed keen evidence that SARS-CoV-2 has evolved from Bat SARS-like coronavirus. The evolutionary history and comparative proteomic analysis provide a new avenue for the current scientific research related to the coronavirus.

Conjugated Proteins
Nucleoproteins are protein complexes that contain nucleic acids, categorized as deoxyribonucleoproteins (DNPs) or ribonucleoproteins (RNPs) respectively. The nucleosome is a typical example of a DNP where nuclear DNA is associated with histone proteins. The major antigen for the Covid-19 virus SARS-CoV is an RNP that is critical...
