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.
What else can I help you with?
What are the three types of capsid?
The three types of capsid are helical, icosahedral, and complex. Helical capsids have a cylindrical shape, icosahedral capsids have a polyhedral shape with 20 equilateral triangular faces, and complex capsids have a combination of both helical and icosahedral elements.
What is the nucleic acid of a virus stored in?
The nucleic acid of a virus is stored in its viral capsid or envelope. The capsid or envelope protects the genetic material of the virus and helps it enter host cells to replicate.
Does H5N1 has a capsid or protein coat?
Yes, H5N1 is an influenza virus, which means it has a protein coat called a capsid surrounding its genetic material. The capsid helps protect the virus and enables it to infect host cells.
A virus's DNA and RNA is surrounded by an?
A virus's DNA and RNA are surrounded by a protein coat called a capsid. This capsid provides protection to the virus's genetic material and helps it to infect host cells. Some viruses also have an additional lipid envelope surrounding the capsid.
Do prokaryotic cells have a Protein Capsid?
No, prokaryotic cells do not have a protein capsid. Protein capsids are a characteristic feature of viruses, which are non-living entities that infect cells. Prokaryotic cells, such as bacteria, are living organisms that do not possess a protein capsid.
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.
What is an optional 3rd viral component that if present will help a virus to enter the host cell?
The three are a capsid, envelope and spikes. The envelope is optional.
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 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 are the three types of capsid?
The three types of capsid are helical, icosahedral, and complex. Helical capsids have a cylindrical shape, icosahedral capsids have a polyhedral shape with 20 equilateral triangular faces, and complex capsids have a combination of both helical and icosahedral elements.
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?
The nucleic acid of a virus is stored in its viral capsid or envelope. The capsid or envelope protects the genetic material of the virus and helps it enter host cells to replicate.
How large is a rhinovirus?
The spherical virus particles have a diameter of 50 to 70 nm and are covered by a lipid membrane. There are prominent "spikes" of 6 nm. Inside the lipid envelope is a capsid of 40 nm in diameter.
Does H5N1 has a capsid or protein coat?
Yes, H5N1 is an influenza virus, which means it has a protein coat called a capsid surrounding its genetic material. The capsid helps protect the virus and enables it to infect host cells.
What is responsible for the flu?
influenza capsid
Which protects the DNA of a virus?
Capsid
What protect the DNA of a virus?
Capsid
