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.
While each vehicle reaches its optimal fuel economy at a different speed (or range of speeds), gas mileage usually decreases rapidly speeds above 55 miles per hour. Just slowing down from 65 mph to 55 mph can increase your miles per gallon by as much as 15 percent.According to the U.S. Department of Energy (DOE), as a rule of thumb, you can assume that each 5 mph you drive over 60 mph is like paying an additional $0.21 per gallon for gas (at $3.00 per gallon).hile each vehicle reaches its optimal fuel economy at a different speed (or range of speeds), gas mileage usually decreases rapidly speeds above 55 miles per hour.
