Guida verificata passo dopo passo1
Understand the structure of nucleic acids: DNA and RNA are both nucleic acids composed of nucleotides, which include a sugar, a phosphate group, and a nitrogenous base.
Identify the nitrogenous bases in DNA: DNA contains four nitrogenous bases: Adenine (A), Thymine (T), Cytosine (C), and Guanine (G).
Identify the nitrogenous bases in RNA: RNA also contains four nitrogenous bases, but instead of Thymine, it has Uracil (U). The bases in RNA are Adenine (A), Uracil (U), Cytosine (C), and Guanine (G).
Compare the bases in DNA and RNA: Notice that Thymine is present in DNA but not in RNA, while Uracil is present in RNA but not in DNA.
Conclude which base is unique to RNA: Based on the comparison, Uracil is the nitrogenous base found in RNA but not in DNA.
