Question

viruses are not considered organisms, because they lack many of the characteristics of living things. a virus is essentially a string of genetic material in a protein coat. some viruses contain dna, while others, called retroviruses, contain rna. one example of a retrovirus is hiv, which causes aids. how is rna different from dna? choose the 2 statements that apply. a. dna and rna use different sets of nitrogen bases. b. dna has 1 strand of genetic material while rna has 2 strands. c. dna contains deoxyribose sugar and rna contains ribose sugar. d. dna and rna are proteins.

Explanation:

DNA has two strands while RNA is usually single - stranded. DNA contains deoxyribose sugar and RNA contains ribose sugar. DNA and RNA use different sets of nitrogen bases. DNA is double - stranded genetic material and RNA is usually single - stranded. DNA has deoxyribose and RNA has ribose.

Answer:

A. DNA and RNA use different sets of nitrogen bases.
C. DNA contains deoxyribose sugar and RNA contains ribose sugar.
