Which of the following describes a difference between DNA and RNA?
A
RNA is more stable than DNA under alkaline conditions.
B
DNA is single-stranded, while RNA is double-stranded.
C
RNA contains uracil, while DNA contains thymine.
D
DNA contains ribose sugar, while RNA contains deoxyribose 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.
Examine the nitrogenous bases: DNA contains the bases adenine, guanine, cytosine, and thymine, whereas RNA contains adenine, guanine, cytosine, and uracil instead of thymine.
Consider the stability under alkaline conditions: DNA is generally more stable than RNA under alkaline conditions due to the absence of the 2'-hydroxyl group in deoxyribose, which makes RNA more prone to hydrolysis.
Review the strand structure: DNA is typically double-stranded, forming a double helix, while RNA is usually single-stranded, allowing it to fold into various shapes for different functions.
