Verified step by step guidance
1
Understand the basic structure of nucleotides in nucleic acids. Nucleotides are the building blocks of nucleic acids like DNA and RNA, consisting of a sugar, a phosphate group, and a nitrogenous base.
Identify the nitrogenous bases present in DNA. DNA contains four main bases: Adenine (A), Thymine (T), Cytosine (C), and Guanine (G).
Identify the nitrogenous bases present in RNA. RNA also contains four main bases: Adenine (A), Uracil (U), Cytosine (C), and Guanine (G).
Compare the bases in DNA and RNA to determine which base is unique to RNA. Notice that Uracil (U) is present in RNA but not in DNA, where Thymine (T) is used instead.
Conclude that Uracil is the nucleotide unique to RNA, replacing Thymine found in DNA.
