From the sandy creek in the Cajon Pass, into Lone Pine Canyon, up and along the Blue Ridge to the summit of Mt. Baden-Powell, then edging along to Islip Saddle, the trail within proximatey to Wrightwood provides views of the extended metropolitan areas of Southern California and the Mojave Desert.
Guanine, along with adenine and cytosine, is present in both DNA and RNA, whereas thymine is usually seen only in DNA, and uracil only in RNA. Guanine has two tautomeric forms, the major keto form (see figures) and rare enol form. It binds to cytosine through three hydrogen bonds.
They are cytosine, adenine, guanine, uracil and thymine . Each nucleotide contains one of the five organic bases. Guanine, cytosine and adenine are found in both DNA and RNA molecules, whereas thymine is found only in DNA and RNA contains only uracil of these five organic bases. All five of the bases comprises complex ring structure made up of nitrogen and carbon atoms.
