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.
One side registers the minimum temperature, while the other registers the maximum temperature since its last reading. The bend at the bottom of the thermometer contains the liquid mercury, which moves up and down based on contractions of the oil or alcohol located in the two bulbs at the top of the thermometer.
