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.
Most often thermometers use mercury, but alcohol could be used as well since it has a very low freezing point (-114Â°C). You cannot use water in a thermometer because it wil â¦ l freeze at 0Â°C rendering the use of a thermometer impossible when it's freezing outside.ercury has a higher boiling point and hence would not evaporate after 100 degree Celsius, like water, and this enables us to measure temperatures beyond it but if we see that as mercury is an good conductor of heat and it is expand to its level when we heat.
