What kind of structure is a virus made of?
What kind of structure is a virus made of?
The structure resulting from the combination of the capsid and the nucleic acid genome is called the nucleocapsid. A single, fully assembled, infectious virus particle is called a virion. Viruses strive to be as simple as possible while still maintaining their basic function, a concept that scientists call genetic economy.
How are viruses unique to other living things?
They are unique because they are only alive and able to multiply inside the cells of other living things. The cell they multiply in is called the host cell. A virus is made up of a core of genetic material, either DNA or RNA, surrounded by a protective coat called a capsid which is made up of protein.
What do you call a virus that infects only bacteria?
The fact that the host range — the group of cell types that a viruscan infect — is generally restricted serves as a basis for classifying viruses. A virus that infects only bacteria is called a bacteriophage,
What is the protein coat of a virus called?
This protein coat is called a capsid, and the instructions for making the protein subunits of the capsid are encoded in the nucleic acid genome of the virus. The structure resulting from the combination of the capsid and the nucleic acid genome is called the nucleocapsid. A single, fully assembled, infectious virus particle is called a virion.
What makes up the core of a virus?
A virus is made up of a core of genetic material, either DNA or RNA, surrounded by a protective coat called a capsid which is made up of protein. Sometimes the capsid is surrounded by an additional spikey coat called the envelope. Viruses are capable of latching onto host cells and getting inside them. H3N2 influenza virus particles, coloured

How are virus particles made out of cells?
Viruses are not made out of cells. A single virus particle is known as a virion, and is made up of a set of genes bundled within a protective protein shell called a capsid. Certain virus strains will have an extra membrane (lipid bilayer) surrounding it called an envelope.
What kind of DNA does a virus contain?
Class I viruses contain a single molecule of double-stranded DNA (dsDNA). In the case of the most common type of class I animal virus, viral DNA enters the cell nucleus, where cellular enzymes transcribe the DNA and process the resulting RNA into viral mRNA. Examples of these viruses include the following:
