What is the primary structural difference between DNA and RNA?
What is the primary structural difference between DNA and RNA?
The primary structural difference is that DNA contains deoxyribose sugar, while RNA contains ribose sugar.
Explain how the double helix structure of DNA contributes to its stability.
Explain how the double helix structure of DNA contributes to its stability.
The double helix structure provides stability through hydrogen bonds between base pairs and the complementary nature of the strands.
Describe the function of messenger RNA (mRNA) in protein synthesis.
Describe the function of messenger RNA (mRNA) in protein synthesis.
mRNA serves as a template for translating genetic information into a specific sequence of amino acids in a protein.

Study Notes
DNA vs. RNA Structure
- DNA is a double-stranded helix, while RNA is a single-stranded helix.
- DNA contains deoxyribose sugar, while RNA contains ribose sugar.
- DNA uses thymine (T) as a base, while RNA uses uracil (U).
DNA Double Helix Stability
- The double helix structure of DNA is stabilized by hydrogen bonds between complementary base pairs (A-T and G-C).
- These bonds create a strong, stable structure, crucial for storing and transmitting genetic information.
Messenger RNA (mRNA) Function
- mRNA carries genetic information from DNA in the nucleus to ribosomes in the cytoplasm.
- This information is used to direct protein synthesis.
Nucleotide Role
- Nucleotides are the building blocks of nucleic acids (DNA and RNA)
- They consist of a sugar molecule, a phosphate group, and a nitrogenous base.
- Their sequence determines the genetic code.
Base Pairing Rules
- In DNA, adenine (A) pairs with thymine (T) and guanine (G) pairs with cytosine (C).
- In RNA, adenine (A) pairs with uracil (U) and guanine (G) pairs with cytosine (C).
- These differences allow RNA to form different structures and function in diverse ways compared to DNA.
