Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
The protein coat, or capsid, is encoded within the viral genone of each virus, and therefore the virus contains the information for the structure of the capsid and not the host cell. Which of the following if a type of viral capsid?
A
icosahedral
B
filamentous
C
head-tail
D
icosahedral, filamentous, head-tail
Explanation: 

Detailed explanation-1: -However, all virus particles have a protein coat that surrounds and protects a nucleic acid genome. This protein coat is called a capsid, and the instructions for making the protein subunits of the capsid are encoded in the nucleic acid genome of the virus.

Detailed explanation-2: -The capsid is made from the proteins that are encoded by viral genes within their genome. The shape of the capsid serves as one basis for classification of viruses.

Detailed explanation-3: -Viruses have a protein coat called capsid, that encloses their genetic material.

Detailed explanation-4: -A primary function of the capsid is to protect the viral genome from environmental conditions and ultimately to deliver the genome to the interior of a homologous host cell.
