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.
cytosine, C-a base found in DNA and RNA and derived from pyrimidine; pairs with guanine. informational RNA, messenger RNA, mRNA, template RNA-the template for protein synthesis; the form of RNA that carries information from DNA in the nucleus to the ribosome sites of protein synthesis in the cell.. A nucleic acid present in all living cells and many viruses, consisting of a long, usually single-stranded chain of alternating phosphate and ribose units, with one of the bases adenine, guanine, cytosine, or uracil bonded to each ribose molecule.
