Answer

Brief Explanations:

DNA is a nucleic - acid polymer. Its building blocks are nucleotides, which consist of a sugar, a phosphate group, and a nitrogen - containing base. Structurally, DNA has a double - helix appearance, discovered by Watson and Crick. Adenines are one of the nitrogenous bases in DNA, and amino acids are the building blocks of proteins. A single strand is not the typical appearance of DNA in cells, and letter U is related to RNA (uracil) not DNA's structure, and triple helix and circle are not the common forms of DNA.

Answer:

Part A: C. nucleotides Part B: C. double helix
