Nucleic acids, which include DNA (deoxyribonucleic acid) and RNA (ribonucleic acid), are made from monomers known as nucleotides. Each nucleotide has three components: a 5-carbon sugar, a phosphate group, and a nitrogenous base.If the sugar is deoxyribose, the polymer is DNA.If the sugar is ribose, the polymer is RNA.ucleic acids, which include DNA (deoxyribonucleic acid) and RNA (ribonucleic acid), are made from monomers known as nucleotides.

The standard inline skates bearings have the designation 608. The 608 means that the bearings are from the 600 series, with a 8mm inner diameter (the width of the hole, i.e., internal bore). The 6 appears to be for the 6mm difference between the inner and outer radii (from the outside edge to the edge of the hole). 608 bearings are also the standard size for skateboard bearings. Quad skates use either type 608 (8mm internal bore) or type 627 (7mm internal bore).
