Synthesis DNA structure Complete the following paragraph to describe the structure of DNA discovered that DNA is a chain of building in the early 1950s blocks called hexose thymine Each nucleotide is comprised of three subunits: phosphoric acid (phosphate), a sugar, and a nitrogenous base. sugar examples of The nitrogenous bases tound in DNA are either which are adenine and guanine, or guanine Watson and Crick spirochete pyrimidines purines such as thymine and The phosphate and sugar make up the bases are attached to the of the strand. of the DNA, while the molecules and project to one side Because of this positoning, complementary base pairing can occur where adenine on one DNA strand forms a hydrogen bond with strand. Pairing occurs between on the other DNA as well. pentose ytosine and Avery and Oswald Such base pairing between As and Ts, and Cs and Gs creates a twisted duplex o' DNA called a antiparane Finaly, the two strands of the DNA double helix are they run in opposite drections as noted by the orientation of the sugar molecules in each strand parallel double helo Reset lot 20 ¡¡¡¡: Score answer >Explanation / Answer
