Wrightwood, located about 360 miles from Mexico along the PCT, is a popular stopover and supply point for hikers on the long walk through the backcountry, as well as an entry point for those challenging portions of the trail on shorter backpacking trips and day hikes.
Cytosine thymine guanine and adenine are the nitrogenous bases found in the nucleotides that form DNA.DNA is made up of 3 parts:(1)Phosphate group(2)Deoxyribose(3)Nitrogen containing base.Complimentary pairing/ bonding through weak hydrogen bonds occurs between Cytosine and Guanine(first pair) and Adenine and Thymine.ytosine thymine guanine and adenine are the nitrogenous bases found in the nucleotides that form DNA.DNA is made up of 3 parts:(1)Phosphate group(2)Deoxyribose(3)Nitrogen containing base.Complimentary pairing/ bonding through weak hydrogen bonds occurs between Cytosine and Guanine(first pair) and Adenine and Thymine.
Image Credit: Main Image: Cytosine is one of the four main bases found in DNA (deoxyribonucleic acid) and RNA (ribonucleic acid), along with adenine, guanine, and thymine. Cytosine is one of the 5 nitrogenous bases that are attached to a 5 carbon sugar, pentose and a phosphate group to make nucleotides.ach nucleotide has three parts-a five carbon sugar, a phosphate group and an organic base. There are 2 variations of the sugar, depending on whether the nucleotide is in a DNA or RNA molecule. One of five different organic bases can be attached to each nucleotide-adenine, cytosine, guanine, thymine or uracil.
