The covering that protects the DNA of a virus is called a capsid. This protein coat encases and safeguards the viral genetic material, whether it is DNA or RNA, from environmental threats and helps the virus attach to and enter host cells. In some viruses, the capsid is further surrounded by an additional lipid envelope derived from the host cell membrane, which also plays a role in infection.
Capsid
A virus has either DNA or RNA inside the covering called a capsid.
virus consist of two layers: 1. its inner layer is made up of DNA. 2. whereas its outer layer or covering is made up of PROTEIN.......and such virus is known as BACTERIOPHAGE VIRUS
Every virus has genetic material (DNA or RNA) and a protein coat (capsid) that protects the genetic material.
A DNA virus has only DNA as its genetic material.
Cytomegalovirus (CMV) is a DNA virus. It has a large double-stranded DNA genome.
What a cell and a virus have in common is the RNA or DNA. The virus can be either a RNA virus or a DNA virus.
The cell membrane is the outer covering of a cell, protects it and maintains the shape of the cell.
DNA+DNA=virus
DNA+DNA=virus
AIDS is not a virus. However, HIV is a RNA virus.
HIV is an RNA-virus. It does not contain DNA.
