검증된 단계별 안내1
Understand that DNA and RNA are nucleic acids, which are essential macromolecules in biological systems.
Recognize that the basic building blocks of nucleic acids are nucleotides.
Identify the three components of a nucleotide: a sugar, a phosphate group, and a nitrogenous base.
Differentiate between the sugars in DNA and RNA: DNA contains deoxyribose, while RNA contains ribose.
Note the types of nitrogenous bases: DNA includes adenine, thymine, cytosine, and guanine, whereas RNA includes adenine, uracil, cytosine, and guanine.
