The DNA molecule is a polymer consisting of several thousand pairs of nucleotide monomers. Each nucleotide consists of the pentose sugar deoxyribose, a phosphate group and a nitrogenous base which may be either a purine or a pyrimidine. Deoxyribose and a nitrogenous base together form a nucleoside.he DNA molecule is a polymer consisting of several thousand pairs of nucleotide monomers.

One way to measure the temperature of matter is. to place a thermometer in contact with it. Some of the. matterâs kinetic energy is transferred to the thermometer. if the matter is warmer than the thermometer. The. increased kinetic energy causes the particles of the. liquid in the thermometer to move farther away from. each other.
The theoretical basis for thermometers is the zeroth law of thermodynamics which postulates that if you have three bodies, A, B and C, if A and B are at the same temperature, and B and C are at the same temperature then A and C are at the same temperature. B, of course, is the thermometer.
