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 Ups and Downs of Thermometers. 1  The way a thermometer works is an example of heating and cooling a liquid.  When heated, the molecules of the liquid in the thermometer move faster, causing them to get a little further apart. This results in movement up the thermometer.
