You arrive late to a biological seminar. However, just as you enter the room, you hear the speaker referring to the "five-prime end" and the "three-prime end" of a macromolecule. Immediately, you know she is referring to: Group of answer choicesa. a carbohydrateb. a proteinsc. DNAd. a lipid

c. DNA

Explanation:

The DNA is double stranded molecule that twist around each other to form a double helix structure. Each strand consists of nucleotide bases joined together by deoxyribose sugar-phosphate backbone.

The two strands of the DNA lies anti-parallel to each other and each strand has two ends - the 5' end where the phosphate group gets attached to the 5′ carbon of a ribose sugar and the 3' end where there is a free hydroxyl group attached to the 3′ carbon of a ribose sugar.

Hence, the correct option is c.
