Question

All viruses contain

• A. Protein coat
• B. Cell membrane
• C. Membrane-bound organelles
• D. Endoplasmic Reticulum
• E. Mitochondrial DNA

Answer 1

The correct option is A Protein coat

Viruses are intracellular obligatory parasitic, self-replicating non-cellular, sub-microscopic organisms. They lack cellular organelles like ribosomes, mitochondria, etc. A simple virus particle, often called as a virion, consists of a nucleic acid core of genetic material, enclosed within a protein coat (capsid). The capsid consists of several identical protein subunits known as capsomeres. The amount of protein content differs in different types of viruses.

So, the correct answer is option A.
