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.
Guanine, which is yellow forms a complement with cytosine, which is blue. Note the specific way in which the different nitrogenous bases are paired. The adenine-thymine (A-T for short) pair is formed by two hydrogen bonds and the guanine-cytosine (G-C) base pair has 3 hydrogen bonds. Adenine can only bond with thymine and vice-versa. In the same fashion, guanine and cytosine can only bond with each other.
