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.
These cars compete in a 1/4 mile (0.4 km) race and complete it in less than 4.5 seconds at upwards of 330 mph (530 km/h). A Top Fuel dragster accelerates from 0 to 100 mph (160 km/h) in less than 0.8 second, subjecting the driver to a force about 5.7 times his weight.he nitromethane used to power the engines of top fuel dragsters costs about US$30 per U.S. gallon (US$8/L). Top Fuel dragsters use between 10 and 12 U.S. gallons (38 to 45 L) of fuel for a complete pass, including the burnout, backup to the starting line, and quarter-mile run.
