Common mistake
Confusing DNA Nucleotide Components
Students often confuse the components of DNA nucleotides, such as mixing up the sugar and phosphate groups.
Remember that a DNA nucleotide consists of a deoxyribose sugar, a phosphate group, and a nitrogenous base. Clearly label each component when drawing or describing nucleotides.
