Which of the following statements accurately describes a difference between DNA and RNA?
A
DNA uses uracil as a base, while RNA uses thymine.
B
DNA is single-stranded, while RNA is double-stranded.
C
DNA is found only in the cytoplasm, while RNA is found only in the nucleus.
D
DNA contains deoxyribose sugar, while RNA contains ribose sugar.
Verified step by step guidance1
Understand the basic structure of nucleic acids: DNA and RNA are both nucleic acids composed of nucleotides, which include a sugar, a phosphate group, and a nitrogenous base.
Identify the sugar component: DNA contains deoxyribose sugar, which lacks one oxygen atom compared to the ribose sugar found in RNA.
Recognize the nitrogenous bases: DNA uses adenine, thymine, cytosine, and guanine as its bases, while RNA uses adenine, uracil, cytosine, and guanine.
Distinguish the strand structure: DNA is typically double-stranded, forming a double helix, whereas RNA is usually single-stranded.
Clarify the location within the cell: DNA is primarily located in the nucleus, while RNA can be found in both the nucleus and the cytoplasm, where it plays a role in protein synthesis.
