1.6 Nucleic Acids

• The pentose sugar in DNA is deoxyribose
• Match the feature with the correct nucleic acid:

  Deoxyribose ↔️ DNA

  Ribose ↔️ RNA
• The primary function of RNA is protein synthesis
• Which nitrogenous base pairs with adenine in DNA?

  Thymine
• The pentose sugar in RNA is ribose
• Arrange the components of a nucleotide in the correct order:

  1️⃣ Pentose sugar

  2️⃣ Phosphate group

  3️⃣ Nitrogenous base
• In DNA, cytosine pairs with guanine
• The double helix structure of DNA is formed by complementary base pairing.


  True
• The two polynucleotide strands in DNA are held together by hydrogen bonds between complementary base pairs
• Match the type of RNA with its function:

  mRNA ↔️ Carries genetic instructions

  tRNA ↔️ Transports amino acids

  rRNA ↔️ Structural component of ribosomes
• DNA contains deoxyribose as its pentose sugar, while RNA contains ribose.


  True
• Match the component with its type in DNA and RNA:

  Pentose Sugar in DNA ↔️ Deoxyribose

  Pentose Sugar in RNA ↔️ Ribose

  Nitrogenous Base in DNA ↔️ Thymine

  Nitrogenous Base in RNA ↔️ Uracil
• In DNA, adenine is always paired with thymine
• What replaces thymine in RNA?

  Uracil
• RNA is a single-stranded nucleic acid that contains ribose instead of deoxyribose.


  True
