entire bicycle network, consisting of over 300 miles of bikeways would cost $60 million to replace (2008 dollars), whereas the same investment would yield just one mile of a four-lane urban freeway. 1
Nucleotides in DNA contain four different nitrogenous bases: Thymine, Cytosine, Adenine, or Guanine. Pyrimidines: Cytosine and Thymine each have a single six-member ring. Purines: Guanine and Adenine each have a double ring made up of a five-atom ring attached by one side to a six-atom ring. The order of nucleotides along DNA polymers encode the genetic information carried by DNA. DNA polymers can be tens of millions of nucleotides long.
Best Answer: RNA is made of RNA nucleotides. Each nucleotide has a sugar (ribose), a phosphate, and a nitrogen base (adenine, uracil, cytosine, or guanine). The overall shape of a nucleotide is kind of like an L.Source(s): http://www.austincc.edu/muzos/RNA%201%20...ach nucleotide has a sugar (ribose), a phosphate, and a nitrogen base (adenine, uracil, cytosine, or guanine).
