Quizplus · Accepted Answer

The 5' end of a DNA strand has a phosphate group attached to the 5' carbon of the deoxyribose sugar in the nucleotide, while the 3' end has a hydroxyl group attached to the 3' carbon of the deoxyribose sugar in the nucleotide. This is important for DNA replication and the formation of phosphodiester bonds between nucleotides.
