The correct response is chromosome. A chromosome contains a single, long DNA molecule that is packaged with proteins to form a compact structure. Nucleotides are the building blocks of DNA, and genes are segments of DNA that encode for proteins or RNA, but they do not refer to the entire long DNA molecule that a chromosome consists of. Deoxyribose is a sugar component of DNA, but it is not a DNA molecule itself.
Which of these contains a single, long DNA molecule?
