Dec 12, 2021 · Severe acute respiratory syndrome coronavirus 2 ( SARS-CoV-2 ), also known as “the novel coronavirus” due to genome variation relative to previously identified coronaviruses, is a positive sense RNA virus and the etiological agent of COVID-19.
SARS-CoV-2 has a linear, positive-sense, single-stranded RNA genome about 30,000 bases long. Its genome has a bias against cytosine (C) and guanine (G) nucleotides , like other coronaviruses. [153] The genome has the highest composition of U (32.2%), followed by A (29.9%), and a similar composition of G (19.6%) and C (18.3%). [154]

Dec 20, 2023 · For diagnosing current SARS-CoV-2 infection, the Centers for Disease Control and Prevention (CDC) recommends using either a nucleic acid amplification test (NAAT) or an antigen test. 1 Testing may also be used for screening and to determine the length of a patient’s isolation period. 2 There may be a window period of up to 5 days after exposure ...

Nov 25, 2021 · Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has killed millions of people and continues to cause massive global upheaval. Coronaviruses are positive-strand RNA viruses...
May 11, 2021 · The SARS-CoV-2 genome consists of nearly 30,000 RNA bases. Scientists have identified several regions known to encode protein-coding genes, based on their similarity to protein-coding genes found in related viruses. A few other regions were suspected to encode proteins, but they had not been definitively classified as protein-coding genes.
