Multiple Choice
Which of these is a difference between a DNA and an RNA molecule?
A
DNA uses uracil as a base, while RNA uses thymine.
B
DNA is found only in the cytoplasm, while RNA is found only in the nucleus.
C
DNA is single-stranded, while RNA is double-stranded.
D
DNA contains deoxyribose sugar, while RNA contains ribose sugar.
Verified step by step guidance
1
Identify the structural components of DNA and RNA molecules. DNA contains the sugar deoxyribose, while RNA contains the sugar ribose.
Understand the nitrogenous bases used in DNA and RNA. DNA uses adenine, thymine, cytosine, and guanine, whereas RNA uses adenine, uracil, cytosine, and guanine.
Recognize the structural form of DNA and RNA. DNA is typically double-stranded, forming a double helix, while RNA is usually single-stranded.
Consider the cellular location of DNA and RNA. DNA is primarily located in the nucleus, while RNA can be found in both the nucleus and the cytoplasm.
Evaluate the given options based on these differences to determine the correct statement: DNA contains deoxyribose sugar, while RNA contains ribose sugar.
