Which statement describes one way that rna differs from dna?

DNA contains the bases Adenine Thymine Guanine and Cytosine, whereas RNA contains the bases Adenine Uracil Guanine and Cytosine.

Explanation:

DNA is an organic compound whose molecules contain the genetic instructions that coordinate the development and functioning of all living things and some viruses.  DNA genes are expressed through the proteins their nucleotides produce with the help of RNA.  DNA has the function of storing genetic information, controlling cellular activity and producing RNA.  It also has helical chains with thousands of nucleotides and its nitrogenous bases are cytosine, guanine, adenine and thymine.

On the other hand, RNA is a nucleic acid responsible for the synthesis of cell proteins. The various forms of RNA synthesize these proteins according to the information contained in DNA.  RNA has the function of synthesizing proteins and transferring information from DNA to the protein synthesis site in the cell.  Moreover, it has only one nucleotide-filled helical chain and its nitrogenous bases are cytosine, guanine, adenine and uracil.
