Varicella zoster virus, also known as human herpesvirus 3, has double stranded DNA for its genome, and is about 125000 nucleotides long.
The virus looks very much like a fried egg under the electron microscope. It has a lipid membrane, and is about 120-200 nm in diameter.

What does the shape of a protein resembles?
Proteins are "folded" molecules there is not one shape, each protein is different. ---------------------------------------------------------------------------------------------- A protein has a primary structure which folds into a secondary structure (alpha helix or B-sheet) and then has a tertiary structure (its 3D fold). Many proteins can complex together to create a quaternary structure. ---------------------------------------------------------------------------------- Depending on the type of protein and the environment that the protein is in determines its "shape". The hydrophobic effect plays a huge role in this. Membrane proteins are in a hydrophobic environment, and cytosolic proteins are in a hydrophilic environment. ------------------------------------------------------------------------------------------------ If you are referring to an amino acid which is a polypeptide monomer, then amino acids have a tetrahedral shape around the alpha carbon. ---------------------------------------------------------------------------------- also known as a messy group of coat hangers
What is the structure of typical virus?
a typical virus has a core of DNA or RNA and a protein coat
Does the shape of the protein allow the virus coat to attached to certain cell in the host?
yes
Do animal cells have a protein coat?
No, animal cells do not have a protein coat. Only viruses have a protein coat.
Does the shape of the protein allows the virus coat to attach to only certain cells in the host?
yes
Do animal cells have protein coat?
No they do not have a protein coat
Do viruses have a protein coat?
no
2 parts of a virus?
capsid (= protein coat) and nucleic acid - DNA or RNA.
Does a virus' coat contain protein?
If a virus has one, yes, and it's often referred to as a "protein coat."
What is the physical description of the polio virus?
The mature virus has a bullet shape, a protein coat, and a lipid envelope. The outer surface of the virus is covered with thumblike glycoprotein projections 5-10 nm long and 3 nm in diameter. The virus averages approximately 780 nm in length.
Are bacteria and viruses surrounded by a protein coat?
No - They are surrounded by a protein coat called the capsid
What is a virus's coat?
protein
