Which of the following is not a difference between DNA and RNA?
A
RNA uses ribose, DNA uses deoxyribose
B
RNA uses uracil, DNA uses thymine
C
RNA uses Phosphodiester bonds, DNA uses ester bonds
D
RNA is normally single stranded, DNA is normally double stranded
Verified step by step guidance1
Identify the structural components of DNA and RNA: DNA contains deoxyribose sugar, while RNA contains ribose sugar.
Examine the nitrogenous bases: DNA uses thymine, whereas RNA uses uracil.
Consider the typical structure: DNA is usually double-stranded, forming a double helix, while RNA is typically single-stranded.
Understand the type of bonds: Both DNA and RNA use phosphodiester bonds to link nucleotides together in their backbone.
Recognize the incorrect statement: The statement 'RNA uses Phosphodiester bonds, DNA uses ester bonds' is incorrect because both DNA and RNA use phosphodiester bonds.
