1.6 Nucleic Acids

• What are nucleic acids composed of?

  Nucleotides
• DNA is typically double-stranded, while RNA is single-stranded.


  True
• DNA uses thymine (T), while RNA uses uracil (U).
• DNA is double-stranded, while RNA is typically single-stranded.


  True
• Match the sugar with its nucleic acid:

  Deoxyribose ↔️ DNA

  Ribose ↔️ RNA
• RNA is typically single-stranded.

  True
• Match the nitrogenous base with its pairing in DNA:

  Adenine (A) ↔️ Thymine (T)

  Guanine (G) ↔️ Cytosine (C)
• The two strands of the DNA double helix run in antiparallel directions.


  True
• Which sugar is found in RNA?

  Ribose
• RNA contains the nitrogenous base uracil
• Match the feature with the corresponding molecule:

  Sugar ↔️ Ribose

  Base ↔️ Uracil

  Strands ↔️ Single-stranded

  Structure ↔️ Complex folded shapes
• DNA is typically double-stranded, while RNA is typically single-stranded.
• Match the feature with the corresponding molecule:

  Sugar ↔️ Deoxyribose (DNA), Ribose (RNA)

  Base ↔️ Thymine (DNA), Uracil (RNA)

  Strands ↔️ Double-stranded (DNA), Single-stranded (RNA)

  Structure ↔️ Double helix (DNA), Various (RNA)
• In DNA, Adenine pairs with thymine
• What is the primary function of DNA?

  Genetic information storage
• What replaces thymine in RNA?

  Uracil
• DNA is single-stranded, while RNA is double-stranded.

  False
• DNA replication allows genetic information to be passed on during cell division
• What can changes in the DNA sequence lead to?

  Mutations
• MicroRNA (miRNA) can inhibit translation by binding to mRNA.

  True
• What type of RNA serves as the template for protein synthesis?

  mRNA
• rRNA is a component of the ribosome structure.


  True
• miRNA binds to mRNA to inhibit translation
• What is the term for RNA molecules that catalyze chemical reactions?

  Ribozymes
• rRNA is part of the ribosome structure and facilitates protein synthesis.


  True
• DNA contains the sugar deoxyribose, while RNA contains the sugar ribose
• How many strands does DNA have compared to RNA?

  Double vs. single
• DNA primarily stores and transmits genetic information
• Nucleic acids are composed of nucleotides linked together in long chains.

  True
• What are the two main types of nucleic acids?

  DNA and RNA
• DNA is double-stranded, while RNA is typically single-stranded.


  True
• DNA is typically double-stranded, while RNA is typically single-stranded.

  True
• DNA stores genetic information
• Which nitrogenous bases are present in DNA but not in RNA?

  Thymine
• Match the function with the correct nucleic acid:

  Stores genetic information ↔️ DNA

  Protein synthesis ↔️ RNA
• Adenine pairs with Thymine via two hydrogen bonds
• Complementary base pairing ensures the stability of the DNA double helix.


  True
• What type of sugar is found in RNA nucleotides?

  Ribose
• DNA's primary function is to store and transmit genetic information.


  True
• Mutations in DNA sequences can lead to alterations in genetic information.
