Question

determine whether each of the following is a characteristic of dna, rna, or both. is single - stranded: contains nitrogenous bases: contains uracil: contains adenine: is double - stranded: is made of nucleotides: contains deoxyribose sugar: done intro

Explanation:

1. Is single - stranded: RNA is usually single - stranded, while DNA is usually double - stranded.
2. Contains nitrogenous bases: Both DNA and RNA contain nitrogenous bases (adenine, guanine, cytosine, and in DNA thymine, in RNA uracil).
3. Contains uracil: Uracil is a characteristic nitrogenous base of RNA, not found in DNA.
4. Contains adenine: Adenine is present in both DNA and RNA.
5. Is double - stranded: DNA is typically double - stranded, RNA is usually single - stranded.
6. Is made of nucleotides: Both DNA and RNA are polynucleotides, made up of nucleotides.
7. Contains deoxyribose sugar: Deoxyribose is the sugar in DNA, while RNA has ribose sugar.

Answer:

Is single - stranded: RNA
Contains nitrogenous bases: both
Contains uracil: RNA
Contains adenine: both
Is double - stranded: DNA
Is made of nucleotides: both
Contains deoxyribose sugar: DNA
