The singlestranded RNA genome of SARSCoV2 contains 291 nucleotides, encoding for 9860 amino acids Although the origin of SARSCoV2 is currently unknown, it is widely postulated to have originated from an animal implicating zoonotic transmission Genomic analyses suggest that SARSCoV2 probably evolved from a strain found in bats Nucleic Acid Just as in cells, the nucleic acid of each virus encodes the genetic information for the synthesis of all proteins While the doublestranded DNA is responsible for this in prokaryotic and eukaryotic cells, only a few groups of viruses use DNA Most viruses maintain all their genetic information with the singlestranded RNA
