What is the function of membrane envelope in a virus?
This membrane envelope is taken from the last victim of the virus as it exits the cell and contains general identification proteins and docking proteins that the virus can use to gain entry to another cell. The AIDS virus use a docking analogue to dock in the CD4 protein docking area of a T-cell, this facilitates it's entry into the T-cell.
What are the spikes and there function in a virus?
Spikes are proteins that are part of the viral capsid/envelope (depending on if the virus is a naked virus or not). It helps with attachment to the host cell. They are derived from their host cell's own proteins (but are not the same as their hosts), and can help in evading the host cell's defenses.
What is the function of spikes on a virus?
The function of spike proteins is to imitate a protein your cells take in to allow the virus access to the nucleus.
What does the membrane envelope do on a virus?

The AIDS virus use a docking analogue to dock in the CD4 protein docking area of a T-cell, this facilitates it's entry into the T-cell.
What is the function of the glycoproteins on the outside of the virus?
Glycoproteins are proteins that contain sugars and polipetides.
What part of the virus remains outside the bacterium?
The proteins in the capsid allow the virus to attach to the "docking stations" proteins of the host cell. This capsid is left behind. If the capsid has an envelope, that is also left behind. The DNA or RNA enters the cell.
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
Where do animal cell viruses take their envelope from?
Howdy fellow user! The envelope of a virus is made of a lipid bilayer derived from the host during the budding stage, basically the exiting stage of a newly made virus particle. Let's do a little rewind. The virus infects the cell to make many copies of itself by using the transcription and translational machinery available there. The virus proteins are translated first. Some of them are envelope proteins that get collected on the surface of the cell in a designated spot so when the virus buds off, it takes the bilayer with the accumulated envelope proteins. Hope you found this response useful! 😄
True or false the envelope surrounding a virus aids the virus in entering the cell and the virus DNA is found in that envelope?
false
Does the rabies virus have an envelope?
Yes, Rabies virus has an envelope of host plasma membrane origin which is embedded with the sole virus spike protein - Glycoprotein.
What are the spikes and what is their function?
A part of the viral envelope/ capsid which are proteins is known as spikes. They help evade the defenses of the host cell are obtained from their protein.
The fact that the outer membrane of the nuclear envelope has bound ribosomes allows one to most reliably conclude that?
at least some of the proteins that function in the nuclear envelope are made by the ribosomes on the nuclear envelope. I promise this is the right answer, i did it on masteringbio two seconds ago.. Good Luck :-)
