A single virus particle or virion comprises simply an inner core of nucleic acid surrounded by either one or two protective shells or capsidsmade of protein. The capsids are built from a number of identical protein subunits in a highly symmetrical arrangement., most usually either a 20 faced solid or icosahedron or as a spiral tube.
The nucleic acid at the core is called the genome and comprises a string of genes that contain coded instructions for making copies of the virus. Depending on virus type its nucleic acid can be either DNA in which there are 2 complimentary intertwined strands of nucleic acid (the double helix) or RNAconsisting of one single strand.
Viruses are the smallest known types of infection agent. They are approximately 50% to 1% of the size of the smallest bacteria from which they differ in having a much simpler structure as well as method of multiplication.
It is arguable scientifically whether viruses are truly living organisms or just a collection of molecules with the capability of self replication under favorable conditions? Their exclusive activity is to invade the cells of other organismswhich they then take over in order to create copies of themself. Outside living cells they are wholly inert and are incapable of activities typical of a life form such as metabolism.

What is shown by the structural formula of a polyatomic ion?
The structural formula of a polyatomic ion shows the arrangement of atoms within the ion, including their connections and bonds. It provides information on the overall charge of the ion and the distribution of electrons within the ion's structure.
A formula that sHow is the arrangement of all bonds in a molecule is called a?
A formula showing the arrangement of all bonds in a molecule is called a structural formula. It uses lines to represent covalent bonds between atoms.
What is the most obvious structural feature of areolar connective tissue?
The most obvious structural feature of areolar connective tissue is its loose arrangement of collagen and elastic fibers. This gives the tissue its "cobweb-like" appearance and provides flexibility and support to surrounding structures. Additionally, areolar connective tissue contains numerous cells, including fibroblasts, which are responsible for producing and maintaining the extracellular matrix.

What do molecular formulas and structural formulas have in common?
Molecular formulas contain no information about the arrangement of atoms. Because of this, one molecular formula can describe a number of different chemical structures. A structural formula is used to indicate not only the number of atoms, but also their arrangement in space.
Three types of isomers?
Three types of isomers are structural isomers (different connectivity of atoms), stereoisomers (same connectivity but different spatial arrangement), and conformational isomers (different spatial arrangement due to rotation around single bonds).
A carbon molecule that has a different arrangement of atoms is know as?
A carbon molecule that has a different arrangement of atoms is know as an isomer. I just took the test!
What is the difference between constitutional isomers and stereoisomers in terms of their structural arrangement and properties?
Constitutional isomers have different structural arrangements of atoms in their molecules, while stereoisomers have the same structural arrangement but differ in the spatial orientation of their atoms. Constitutional isomers have different chemical and physical properties due to their distinct structures, while stereoisomers have similar properties because of their identical structures.
What is the proper arrangement of layers from the lumen of the organ to the outside?
From the lumen of an organ to the outside, the proper arrangement of layers is typically mucosa, submucosa, muscularis, and serosa (or adventitia). This arrangement helps provide structural support, protection, and aid in the function of the organ.
