virus

an infective agent that typically consists of a nucleic acid molecule in a protein coat, is too small to be seen by light microscopy, and is able to multiply only within the living cells of a host

Viruses are not made out of cells. A single virus particle is known as a virion, and is made up of a set of genes bundled within a protective protein shell called a capsid. Certain virus strains will have an extra membrane (lipid bilayer) surrounding it called an envelope.

ribose

a sugar of the pentose class which occurs widely in nature as a constituent of nucleosides and several vitamins and enzymes

RNA is made up of nucleotides, which are ribose sugars attached to nitrogenous bases and phosphate groups. The nitrogenous bases include adenine, guanine, uracil, and cytosine. RNA mostly exists in the single-stranded form, but there are special RNA viruses that are double-stranded.

deoxyribose 

a sugar derived from ribose by replacement of a hydroxyl group by hydrogen

DNA is made of two linked strands that wind around each other to resemble a twisted ladder — a shape known as a double helix. Each strand has a backbone made of alternating sugar (deoxyribose) and phosphate groups. Attached to each sugar is one of four bases: adenine (A), cytosine (C), guanine (G) or thymine (T).

Tententen 

Another name for Giovanni Boccaccio’s Decameron

Since the Decameron has the Greek word for the number ten (δέκα) in its name, and in the work itself there are ten people, each of whom tells a story each of the ten days spent in their final place, I made up a new name for this famous piece. It’s Tententen.
