NEED HELP QUICK Which of the following statements about the structure of DNA is true?
A) It contains adenine, uracil, guanine, cytosine, and phosphorus.

B) It is composed of phosphates, nitrogenous bases, and ribose sugars.
C) It is composed of a single strand that consists of deoxyribose and phosphate.

D) It contains adenine, thymine, guanine, cytosine, and deoxyribose sugar.

D

Explanation:

dna does not contain uracil. (uracil is in RNA)

dna does not have ribose sugars (ribose sugars are in RNA)

dna is not a single strand.

dna contains adenine, thymine, guanine, cytosine, and deoxyribose sugar.

•there must be variation for the particular trait within a population.

•the variation must be inheritable (that is, it must be capable of being passed on from the parents to their offspring).

•individuals with one version of the trait must produce more offspring than those with a different version of the trait.good
