NEET BIOLOGY

Detailed explanation-1: -For some viruses, the capsid is surrounded by lipid bilayer that contains viral proteins, usually including the proteins that enable the virus to bind to the host cells. This lipid and protein structure is called the virus envelope, and is derived from the host cell membranes.

Detailed explanation-2: -Non-enveloped viruses are typically more virulent Since non-enveloped viruses don’t have that extra lipid membrane, cell lysis is the most common exit mode from the host cell.

Detailed explanation-3: -The main component of the viral envelope is the host-derived lipid bilayer.

Detailed explanation-4: -Viruses are either enveloped or non-enveloped. Enveloped viruses contain the viral genome and core proteins wrapped within one or more membranes. These membranes are acquired from the host cell during virus assembly and budding [166].

Detailed explanation-5: -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.
