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.

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
No, animal cells do not have a protein coat. Only viruses have a protein coat.
yes
a typical virus has a core of DNA or RNA and a protein coat
The protein coat that surrounds a virus is called a capsid. It is composed of protein subunits called capsomers and serves to protect the viral genetic material while also aiding in the virus's ability to infect host cells. The capsid plays a crucial role in the virus's structure and function, helping to determine its shape and stability.
yes
No they do not have a protein coat
No, the cell membrane and protein coat are not the same thing. The cell membrane is a phospholipid bilayer that surrounds the cell, providing structure and regulating what goes in and out. A protein coat, on the other hand, is a protective layer made of proteins that surrounds some viruses.
no
Another name for a protein coat is a "capsid." The capsid is the protein shell that encases and protects the genetic material of viruses, playing a crucial role in their structure and function. It is composed of protein subunits called capsomers, which assemble to form the protective layer around the viral genome.
Proteins have a building blocks as amino acids and I think there are about 20 essential amino acids in humans. The structure depends on the series and sequence of the polypeptides arranged which are joined together by covalent bonds and ultimately form a protein. You will know more about it when you take bio or chemistry classes in your school or college respectively.
The protein coat of a virus is called a capsid. It serves to protect the viral genetic material and aids in the attachment and entry of the virus into host cells. The capsid is composed of protein subunits called capsomers, which can vary in shape and arrangement depending on the type of virus.
