Question

Which structures are found in all viruses?

a capsid and genetic material
a protein coat and DNA
a promoter and genetic material
a plasma membrane and protein coat

Answer 1

dude why all of them are A but i would go with the second 1 a protein coat and DNA

Answer 2

The correct answer is option A, a capsid and genetic material

Reason -

The three major parts of a virus are as follows –

a) Protein Capsid – Virus genetic material(genome) is covered by a protein shell which is known as capsid.

b) Lipid Envelope – Further the Protein Capsid (also referred as nucleocapsid) is surrounded by a membrane called as envelope.

c) Viral genome – It mainly consists of single or double stranded DNA or RNA (carry the genetic material) which can be double or single stranded or may have some other form of structure.
