Detailed explanation-1: -Viruses have a protein coat called capsid, that encloses their genetic material.
Detailed explanation-2: -A virus is made up of genetic material that is encased with a protective protein coat called the capsid. The capsid also helps the virus to infect host cells by binding to the host receptor proteins and releasing its genetic material.
Detailed explanation-3: -A capsid is the protein shell of a virus, enclosing its genetic material. It consists of several oligomeric (repeating) structural subunits made of protein called protomers.
Detailed explanation-4: -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.
Detailed explanation-5: -Viruses contain genetic material which is either RNA or DNA. No virus contains both RNA and DNA. Further, this genetic material is of 4 types double-stranded DNA, single-stranded DNA, double-stranded RNA, single-stranded RNA.
