This statement is false. In fact, it is RNA that contains uracil, while DNA does not.
To explain further, the building blocks of nucleic acids—DNA and RNA—are nucleotides. DNA is composed of four nucleotides: adenine (A), cytosine (C), guanine (G), and thymine (T). Notably, thymine is a key component of DNA and pairs with adenine during DNA replication and transcription.
On the other hand, RNA is made up of nucleotides as well, but instead of thymine, it contains uracil (U). This difference is important for several reasons, including the processes of transcription and translation where RNA plays a crucial role. In these processes, uracil pairs with adenine, allowing for the proper synthesis of proteins.
In summary, it is RNA that contains uracil, while DNA contains thymine. Therefore, the statement in question is indeed false.
