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.
The chemistry of the nitrogenous bases is really the key to the function of DNA. It allows something called complementary base pairing. You see, cytosine can form three hydrogen bonds with guanine, and adenine can form two hydrogen bonds with thymine. Or, more simply, C bonds with G and A bonds with T.he phosphate group and sugar are the same in every nucleotide, but there are four different nitrogenous bases: guanine, adenine, thymine and cytosine. They are often abbreviated by the first letter of each nitrogenous base: G, A, T and C.
