Which type of RNA is present in viruses?

An RNA virus is a virus which has (ribonucleic acid) RNA as its genetic material. The nucleic acid is usually single-stranded RNA (ssRNA) but it may be double-stranded RNA (dsRNA).

What is mRNA tRNA and rRNA and their functions?

Messenger RNA (mRNA) molecules carry the coding sequences for protein synthesis and are called transcripts; ribosomal RNA (rRNA) molecules form the core of a cell’s ribosomes (the structures in which protein synthesis takes place); and transfer RNA (tRNA) molecules carry amino acids to the ribosomes during protein …

What type of RNA is rRNA?

Ribosomal ribonucleic acid (rRNA) is a type of non-coding RNA which is the primary component of ribosomes, essential to all cells. rRNA is a ribozyme which carries out protein synthesis in ribosomes.

Which of these contain RNA as the genetic material?

In some viruses, RNA is the genetic meterial. e.g., Tobacco mosaic viruscs, QB bacteriophage, HIV, influenza virus, etc.

What type of virus uses RNA and not DNA as its genetic material?

Retroviruses. A retrovirus is a type of virus that uses RNA as its genetic material, rather than DNA. Upon infecting a cell, it uses an enzyme called reverse transcriptase to create a DNA copy of its RNA, which it inserts into the genome of its host.

What are the 3 RNA types?

Three main types of RNA are involved in protein synthesis. They are messenger RNA (mRNA), transfer RNA (tRNA), and ribosomal RNA (rRNA).

Why is 16S rRNA used to identify bacteria?

Because of the complexity of DNA–DNA hybridization, 16S rRNA gene sequencing is used as a tool to identify bacteria at the species level and assist with differentiating between closely related bacterial species [8]. Many clinical laboratories rely on this method to identify unknown pathogenic strains [19].

Which viruses have RNA as a genetic material?

1.1. RNA Viruses. Human diseases causing RNA viruses include Orthomyxoviruses, Hepatitis C Virus (HCV), Ebola disease, SARS, influenza, polio measles and retrovirus including adult Human T-cell lymphotropic virus type 1 (HTLV-1) and human immunodeficiency virus (HIV).
