DNA molecules are composed of repeating subunits called nucleotides. A nucleotide is made of three parts: a nucleobase, a certain type of sugar (deoxyribose in the case of DNA â¦ nucleotides), and one or more phosphate groups.There are four different nucleobases found in DNA: adenine, cytosine, guanine, and thymine.NA molecules are composed of repeating subunits called nucleotides.

According to multiple studies, the Hummer H2 has an average mileage between 9 and 15 miles per gallon. Due to the potential repercussions of such extremely low gas mileage on the environment, the Hummer brand has long been a popular target for environmentalists.
Divide mileage by fuel usage to see your car's fuel consumption. This tells you how many miles you drove per gallon of gas. For example, if you drove 335 miles before refueling, and you filled your car up with 12 gallons of gas, your fuel consumption was 27.9 miles per gallon, or mpg (335 miles / 12 gallon = 27.9 mpg). For example, if you used 25 gallons of gas, and drove 500 miles during that time, then your average fuel consumption would be 20 miles per gallon (500 miles / 25 gallons = 20 mpg).
