Each dimension and metric has a scope: users, sessions, or actions. In most cases, it only makes sense to combine dimensions and metrics that share the same scope. For example, Sessions is a session-based metric so it can only be used with session-level dimensions like Source or City.
The sides of the DNA latter consist of the sugar deoxyribose and phosphates. The bond between the latter and the nitrogen bases together is known a a nucleotide. Nucleotides a â¦ re molecules that make up the structure of DNA and RNA.he backbone of the DNA molecule is made up of a sugar (deoxyribose) bonded to a phosphate group bonded to another sugar and then another phosphate and so on. These are very s â¦ trong covalent bonds that are not easily broken. 4 people found this useful.
The double helix describes the appearance of double-stranded DNA, which is composed of two linear strands that run opposite to each other, or anti-parallel, and twist together. Each DNA strand within the double helix is a long, linear molecule made of smaller units called nucleotides that form a chain. The chemical backbones of the double helix are made up of sugar and phosphate molecules that are connected by chemical bonds, known as sugar-phosphate backbones.
