Detailed explanation-1: -Retrovirus meaning – It is a group of RNA viruses that inserts a DNA copy of its genome into the host cell in order to replicate. It consists of two concentric outer circles of the lipid bilayer that contains the envelope protein complex embedded in it. The capsid proteins are hexagonal.
Detailed explanation-2: -A retrovirus has a membrane containing glycoproteins, which are able to bind to a receptor protein on a host cell.
Detailed explanation-3: -A retrovirus is a virus that uses RNA as its genomic material. Upon infection with a retrovirus, a cell converts the retroviral RNA into DNA, which in turn is inserted into the DNA of the host cell.
Detailed explanation-4: -A virus is an infectious microbe consisting of a segment of nucleic acid (either DNA or RNA) surrounded by a protein coat. A virus cannot replicate alone; instead, it must infect cells and use components of the host cell to make copies of itself.
Detailed explanation-5: -An RNA virus particle, or virion, consists of an RNA genome (blue) surrounded by a protein coat or capsid (black). Some viruses also have a lipid envelope studded with viral proteins surrounding the capsid (not shown).
