The function of spike proteins is to imitate a protein your cells take in to allow the virus access to the nucleus.
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.
Because HIV is a virus. Viruses have spikes because it is their way of reproducing.
They are not spikes - they are arms. They use these 'arms' to catch other cells to mutate them or eat them.
Spikes on viruses are made up of proteins that are used to attach the virus to host cells. These proteins play a critical role in allowing the virus to enter and infect host cells by binding to specific receptors on the cell membrane.
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.
It function is to make mRNA and acts as a jet preppeled motor to help the virus move.
A virus carries out the function of replication, by hijacking the host cell's machinery to make copies of itself.
The stage of viral reproduction that takes place when the spikes of the virus bind to a specific receptor molecule on the surface of a host cell is known as attachment or adsorption. This step is crucial for the virus to gain entry into the host cell and initiate the infection process.
The collar function in a virus helps the virus attach to host cells by recognizing specific receptors on the cell surface. This attachment is necessary for the virus to enter the host cell and infect it. The collar function can vary between different types of viruses and plays a crucial role in determining host specificity.
The function is to allow "docking" with the host cell.
