What does the protein coat in a virus do?

Answer 1

The capsid surrounds the genetic information of the virus (protects the genome from the environment and aids in attachment of virus to host cell). The capsid is usually inside the viral envelope (which facilitates attachment to host cell receptors), unless the virus is naked (not all viruses have viral envelopes).

Answer 2

The two functions of a virus's protein coat are to protect the genetic material inside and to react with the cell wall of a potential host cell, thus causing the genetic material to be injected into the host cell.

Answer 3

To have the virus to attach to certain cells in the host.
Attachment to the cell surface of the host molecule i.e. HIV's GP120 (glycoprotein 120) binds to CD4 receptor and CXCR4 and CRCR5 receptors. Also is necessary one would assume to protect the viral DNA/RNA.

Answer 4

The protein coat in a virus protects the genetic material inside and helps the virus to attach to and enter host cells. It also plays a role in determining the virus's ability to infect specific cell types.

Answer 5

A protein coat is generally called a capsid, and is made up of proteins. This protein is called capsomers.

Answer 6

protein coat protect the virus

Answer 7

DNA and RNA
