NEET BIOLOGY

Detailed explanation-1: -The virus envelope is known as a capsid. Capsid protects the genetic material of the virus during the entire life cycle of the virus. The capsid is made up of protein containing several oligomeric structural subunits called protomers. Capsid protects the virus from external environmental conditions.

Detailed explanation-2: -A virus that has an outer wrapping or envelope. This envelope comes from the infected cell, or host, in a process called “budding off.” During the budding process, newly formed virus particles become “enveloped” or wrapped in an outer coat that is made from a small piece of the cell’s plasma membrane.

Detailed explanation-3: -The capsid is made up of proteins. The envelope is made up of proteins and phospholipids. The main difference between capsid and envelope is that capsid is the protective coat of the genetic material of the virus whereas envelope is a protective covering of the protein capsid.

Detailed explanation-4: -Antigenic properties. The lipid bilayered viral envelope of Flaviviridae is composed of two proteins, of which protein E is the primary target of the immune response of the host.
