What surrounds a virus?
I take it that you meant to ask what surrounds the genome of the virus. The genome of the virus (be it DNA or RNA) is enclosed within the capsid shell. The capsid shell is made by the oligomerisation of capsid proteins in a specific organised manner. The genome together with the capsid is termed as nucleocapsid. Sometimes the nucleocapsid is surrounded by a phospholipid membrane (of host origin) called the envelope. The viruses which have an envelope are called envelope viruses eg., Chikunguyna virus, Rabies virus, HIV and the viruses without an envelope are called naked viruses eg., Poliovirus, Rotavirus
What must HIV surface protein do to enter a host cell?
The proteins in the capsid allow the virus to attach to the "docking stations" proteins of the host cell.
What is the protein coat the surrounds a virus call?
The protein coat surrounding the nucleic acid of a virus is called the capsid. These are broadly classified according to their structures. Helical (cylindrical) and icosahedral (spherical) are the most common types.
What is the outer layer of a virus composed of?
Outer layer of a virus is called a capsid. It is the shell of protein which protects the nucleic acid, the brain of a virus. Capsid is composed of individual morphological units called capsomers.
What protect the DNA of a virus?
Capsid
Which protects the DNA of a virus?
Capsid
Why is the capsid protein of a of a virus important?
They help the virus attach to the host cell.
What is bacteriophage capsid?
Correct. For APEX it is, A protective shell around a virus.
What is a virus surrounded by?
The nucleic acid of a virus is covered by a protein capsid.
What is the potein coat that surrounds a virus?
This coat is called a capsid. Sometimes these have a lipid envelope.
What is the nucleic acid of a virus stored in?
In its' capsid.
What is the name of the protein that surrounds the virus?
a capsid
