Which of the following is inaccurate in relation to viruses they have nuclei acid core they feature a capsid they seek out a specific host they reproduce independently?
they reproduce independentlyThis is a false statement as viruses need a host cell and it's replicative machinery to reproduce their genetic material.
What viruses cannot?
They can not reproduce without a host as reproductive vector. They have no metabolism and do not preform cellular functions. Viruses are genetic material enclosed in a protein capsid.
What additiional protective layer of protein surrounds some viruses?
This layer is called a capsid. The viruses without one are called naked viruses. The naked virus is can be damaged more readily by things in the environment.
What is the outer layer of a virus composed of?
Outer layer of a virus is called a capsid. It is the shell of protein which protects the nucleic acid, the brain of a virus. Capsid is composed of individual morphological units called capsomers.
What two things are viruses made of?
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.
What is a viruses coat called?
Capsid.
Do viruses have protective shell?
coat or capsid
What parts does a virus contain?
There are different types of viruses .Most bacterial viruses possess capsid , genome , head , tail , tail fibers , end plate and collar . Enveloped animal viruses have envelop around capsid . Genome and capsid are essentially present in all viruses .
What cover virus?
A capsid covers the DNA (or RNA) of viruses.
Do viruses have a protein coat?
no
What 1 thing viruses do to stay alive?
They form a capsid.
What 2 structures do all viruses have?
All viruses have nucleic acid and a protien coat called a capsid
Are helical viruses rod shaped?
Yes, helical viruses have a rod-shaped structure. These viruses consist of a cylindrical or helical capsid that encloses the viral genetic material, which can be DNA or RNA. The helical capsid gives these viruses their rod-shaped appearance.
What is the the outer protein coat of a virus called?
It is called the capsid, and is usually composed of separate sub-units called capsomeres.
Which of the following is inaccurate in relation to viruses they have nuclei acid core they feature a capsid they seek out a specific host they reproduce independently?
they reproduce independentlyThis is a false statement as viruses need a host cell and it's replicative machinery to reproduce their genetic material.
Do all viruses have a capsid?
the capsid is the protein coat of the virus. so yes
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
