What else can I help you with?
What is a core membrane?
A core membrane is a protective layer surrounding the genetic material of a virus. This membrane helps shield the virus's genetic material from external factors and aids in its ability to infect host cells.
Does a virus have cell membranes?
Enveloped viruses do have a membrane that they got from their host. All other viruses do not.
What does surrounds the hereditary material of a virus?
The capsid. Made of protein, and sometimes various types of proteins.
What is the coating around a virus's core made of?
THe outer shell of a virus is called the capsid, and consists of various proteins, which are arranged to enable the virus to enter and control a host cell. These proteins are called protomers and are assembled in units called capsomeres.
What is a naked virus?
A naked virus is a type of virus that lacks an envelope, which is a lipid membrane that surrounds some viruses. Instead, naked viruses consist only of a protein coat called a capsid that encases their genetic material. This structural simplicity makes them generally more resistant to environmental factors like heat and detergents. Common examples of naked viruses include the adenovirus and the poliovirus.
What additional protective layer of protein surrounds some viruses-?
The envelope.
What additiional protective layer of protein surrounds some viruses?
Some viruses have an additional protective layer of protein called a capsid, which encloses their genetic material. The capsid helps protect the virus from environmental conditions and aids in attaching to host cells for infection.
What is the potein coat that surrounds a virus?
This coat is called a capsid. Sometimes these have a lipid envelope.
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 thin transparent skin of an onion cell called?
The thick layer that surrounds onion cells is called the cell wall. This is common in plant cells and is used to block certain ions from entering.
What is the outer layer of the virus that helps it enter its host?
The outer layer of a virus is called the capsid. Some viruses have an envelope over the capsid either one help the virus enter its' host.
What is bacteriophage capsid?
Correct. For APEX it is, A protective shell around a virus.
Is the outer covering of viruses a capsid made of chitin?
No, the outer covering of viruses is not made of chitin. Viruses have a protein coat called a capsid that surrounds their genetic material. Chitin is a structural polysaccharide found in the exoskeletons of insects and crustaceans.
What is the name of the protein that surrounds the virus?
a capsid
What is the protein coat that surrounds a virus called?
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 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
Does a virus has an outer protein coat?
A virus has a protective protein coating called the capsid. The capsid is a cover for the genetic material inside, either RNA or DNA.
