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.
1 Thymine and adenine can only make up a base pair. 2  Guanine and cytosine can only make up a base pair. 3  Therefore, thymine and cytosine would NOT make up a base pair, as is the case with adenine and guanine.
