Which of the following is true about DNA?
A) transfers messages to the ribosomes
B) contains the sugar ribose
C) contains adenine, guanine, uracil, and cytosine
D) is single stranded
E) forms a helix
DNA
Deoxyribonucleic acid, a molecule that carries the genetic instructions used in the growth, development, functioning, and reproduction of all known living organisms.
Ribose
A five-carbon sugar that is a crucial component of RNA (ribonucleic acid) molecules.
Helix
A three-dimensional, spiral shape, common in structural biology, particularly in the structure of proteins and nucleic acids like DNA.

Final Answer :
E
Explanation :
DNA forms a double helix structure. Choice A is incorrect because RNA transfers messages to the ribosomes, not DNA. Choice B is incorrect because DNA contains the sugar deoxyribose, not ribose. Choice C is incorrect because DNA contains thymine instead of uracil (which is found in RNA), and does not contain uracil. Choice D is incorrect because DNA is double stranded, not single stranded.
