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.
No, there are no spikes on the inside of the human skull. The skull is made up of bones that protect the brain, and it is smooth on the inside to provide a surface for the brain to rest against.
There are 4 types of viruses with different shapes. Tobacco Mosaic Virus - Rod-shaped due to its helical capsid. Adenoviruses - Icosahedral capsid with glycoprotein spikes edging out at each vertex. Influenza Viruses - Spherical. Outer envelope studded with glycoprotein spikes. Bacteriophage T4 - Consists of an icosahedral head, a long tail sheath and small tail fibers (leg-like appearance).
A virus particle is composed of a nucleic acid that is surrounded by the capsid (which is the protective layer that is made out of protein). Some viruses can have lipid envelope however, not all viruses have a lipid envelope.
Viruses are composed of two main parts: an outer protein covering called a capsid and an inside core of either DNA or RNA. Not both DNA and RNA. Some of these have an envelope over the capsid. The ones that do not are said to be naked. The proteins in the capsid allow the virus to attach to the "docking stations" proteins of the host cell. The naked viruses are more resistant to changes in the environment.
Viruses are not made, but rather reproduce by hijacking the cells of living organisms such as plants, animals, and bacteria. They enter a host cell, take over its machinery to replicate their genetic material, and assemble new virus particles. This process ultimately leads to the release of these new viruses from the host cell to infect other cells.
Because HIV is a virus. Viruses have spikes because it is their way of reproducing.
The spikes you are referring to I am assuming concern viruses. They are located on the envelope surrounding the capsid, typically made up of the host cell material. The spikes themselves are of protein and match with receptors on the host cell. This is kind of like a key to a door. The virus sheds the envelope when entering the host cell, then sheds the capsid, releasing the nucleic acid (DNA/RNA) causing a viral infection to occur.
spikes.
Your question is unclear but most spikes are made with materials other than gold.
i think its metal.
Bone.
to run faster obviously
No, tissues are made up of cells and viruses are not even cells.
The Stegosaurus had very large, pointy spikes at the end of its tail. These spikes could have been used for defence against predators, like Allosaurus or Ceratosaurus. Its spikes were made of bone.
Inoculations (for immunization) are substances made from weakened viruses or bacteria.
The Stegosaurus's tail spikes are called thagomizers. They have a bony core but may have been covered in a thick layer of keratin.
Vaccines for the prevention of the specific viral infection can be made with inactive "dead" viruses. They are also made with live, but attenuated (weakened), viruses. See more below about vaccines.
