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 Adenine, Thymine, and Uracil can form TWO hydrogen bonds. 2  Guanine and Cytosine can form THREE hydrogen bonds. 3  In nucleic acids (DNA and RNA), nitrogenous bases can bind to each other by hydrogen bonding.4  Guanine binds to Cytosine, and Cytosine binds to Guanine. 5  In DNA, Adenine binds to Thymine. In RNA, Adenine binds to Uracil. 2  These hydrogen-bond interactions between nucleotides C-G and A-T or A-U are referred to as base-pairing or complementary base-pairing. 3  Base-pairing holds the double-stranded DNA molecule together. 4  Base-pairing is necessary for DNA synthesis, RNA synthesis, and Protein synthesis to occur.
