Guida verificata passo dopo passo1
Understand that both DNA and RNA are nucleic acids composed of nucleotides, which include a sugar, a phosphate group, and a nitrogenous base.
Identify the four nitrogenous bases in DNA: adenine (A), thymine (T), cytosine (C), and guanine (G).
Identify the four nitrogenous bases in RNA: adenine (A), uracil (U), cytosine (C), and guanine (G).
Recognize the key difference between DNA and RNA: DNA contains thymine (T), whereas RNA contains uracil (U) instead of thymine.
Conclude that the correct statement is: DNA contains thymine, while RNA contains uracil, highlighting the substitution of uracil for thymine in RNA.
