for its replication and causes various diseases are commonly known as

A) Satellite RNA

B) Helper retrovirus

C) Micro RNA

D) Heterogeneous RNA​

Answer 1

a option si correct mark this I am sure this is correct

Answer 2

Answer:

A) Satellite RNA

Explanation:

What is an RNA satellite?

• Small subviral RNAs known as viral satellite RNAs (satRNAs) rely on the helper virus for reproduction and transmission. The mechanism by which satRNAs reduce helper virus-induced symptoms is still unknown.
• Because satellite RNAs lack a capsid protein, they need helper viral proteins to encapsidate and replicate the genome.
• A polyphyletic category of viruses known as satellite viruses encodes the structural elements of its virions but is unable to complete the infection cycle on its own. Animals, protists, and plants have all been reported to harbour satellite viruses.

RNA:

• A virus that possesses ribonucleic acid (RNA) as its genetic material is referred to as an RNA virus, as opposed to a retrovirus. The nucleic acid is typically single-stranded RNA (ssRNA), while double-stranded RNA is also possible (dsRNA).  Common cold, influenza, SARS, MERS, Covid-19, Dengue virus, hepatitis C, hepatitis E, West Nile fever, Ebola viral disease, rabies, polio, mumps, and measles are among the well-known human illnesses brought on by RNA viruses.
• RNA viruses are categorised by the International Committee on Taxonomy of Viruses (ICTV) as Group III, Group IV, or Group V of the Baltimore classification system. This category does not include Group VI, which includes retroviruses like HIV-1 and HIV-2 that cause AIDS and have RNA genetic material but use DNA as an intermediary in their life cycle.
• As of May 2020, it is thought that all RNA viruses that encode RNA-directed RNA polymerase belong to a monophyletic clade called the realm Riboviria. The majority of these RNA viruses belong to the kingdom Orthornavirae, whereas the other ones are still being classified. [5] Not all RNA viruses are present in the realm; for example, Deltavirus, Asunviroidae, and Pospiviroidae were included in error in 2019, but were removed in 2020.

hence correct answer would be A) Satellite RNA
