capsid is proteinaceous coat made up of small sub-units called capsomers while envelope is made up of small sub-units named as peplomeres, also it may be composed of proteins, fats or lipids

What is the difference between nucleoplasm and nuclear envelope?
The nulear envelope is a membrane that surrounds the entire nucleus while the nucleoplasm is a liquid (like the cytoplasm) that surrounds the chromosomes and the nucleolus within the nuclear envelope.
Are viruses made of protein and lipid membranes?
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.
What are the two major components of a viral particle?
The first two are common to all viruses:1. Nucleic acid core. The nucleic acid core can either be DNA or RNA that makes up the genetic information of the virus. RNA genome only occurs in viruses.2. Capsid. A capsid is the protein coat that protects the nucleic acid from the environment. It also plays a role in how some viruses attach to a host cell.Some have an3. Envelope. An envelope is a membrane bilayer outside their capsid. If a virus does not have an envelope, the virus is called a naked virus. A naked virus is more resistant to changes.
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.
Do viruses feature a capsid?
no
What is the potein coat that surrounds a virus?
This coat is called a capsid. Sometimes these have a lipid envelope.
What surrounds the capsid and helps the virus enter the cell?
envelope
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
How do you classify viruse?
Virus is classified based on four characteristics. They are dimensions of capsid and virion, absence or presence of envelope, symmetry of capsid and nature of nucleic acid.
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.
Is DNA of herpes virus enveloped?
Herpesvirus particles consist of four morphologically distinct structures, the core, capsid, tegument, and envelope.Animal herpes viruses all share some common properties including the capsid, which is wrapped in a lipid bilayer called the envelope.
What part of the virus remains outside the bacterium?
The proteins in the capsid allow the virus to attach to the "docking stations" proteins of the host cell. This capsid is left behind. If the capsid has an envelope, that is also left behind. The DNA or RNA enters the cell.
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 additional protective layer of protein surrounds some viruses-?
The envelope.
A viral capsid is composed of?
it is composed of individual morphological units called capsomers.
What is a peplon?
Peplon or Peplomer is a glycoprotein spike on viral capsid or viral envelope. They only bind to certain receptors.
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 .
