Question

directions: use your notes to help you sort each of the boxes according to whether it is a statement that is true for only dna, only rna, or both molecules (make sure you sort the cards on both sides of the diagram)

contains the sugar deoxyribose
may contain thymine (t)
dna double helix image
made up of nucleotides
may contain adenine (a)
may contain guanine (g)

venn diagram with dna, both, rna sections
dna section:
deoxyribonucleic acid
double stranded
made up of a, c, t & g
dna structure image

both section:
a nucleic acid
made of a sugar, phosphate, and nitrogenous base
may contain cytosine (c)

rna section:
contains the sugar ribose
ribonucleic acid
single stranded
may contain uracil (u)
made up of a, u, c & g

Explanation:

To solve this, we analyze each card based on DNA and RNA characteristics:

Only DNA:

• Contains the sugar deoxyribose: DNA has deoxyribose; RNA has ribose.
• May contain thymine (T): DNA uses T; RNA uses U.
• Double - helix image (the DNA structure): DNA is double - stranded (helix); RNA is single - stranded.
• Made up of A, C, T & G: DNA’s nitrogenous bases are A, T, C, G.

Both DNA and RNA:

• Made up of nucleotides: Both are nucleic acids, and nucleic acids are made of nucleotides.
• May contain adenine (A): A is a nitrogenous base present in both DNA and RNA.
• May contain guanine (G): G is a nitrogenous base present in both DNA and RNA.
• A nucleic acid: Both DNA and RNA are nucleic acids.
• Made of a sugar, phosphate, and nitrogenous base: The structure of a nucleotide (the building block of both) has a sugar, phosphate, and nitrogenous base.
• May contain cytosine (C): C is a nitrogenous base present in both DNA and RNA.

Only RNA:

• Contains the sugar ribose: RNA has ribose; DNA has deoxyribose.
• Ribonucleic Acid: This is the name of RNA (DNA is Deoxyribonucleic Acid).
• Single - stranded: RNA is single - stranded; DNA is double - stranded.
• May contain uracil (U): RNA uses U; DNA uses T.
• Made up of A, U, C & G: RNA’s nitrogenous bases are A, U, C, G.

Final Sorting:

• DNA only: Contains the sugar deoxyribose, May contain thymine (T), Double - helix image, Made up of A, C, T & G, Double Stranded (from the Venn diagram, this also belongs here as DNA is double - stranded), Deoxyribonucleic Acid (from the Venn diagram, this is DNA’s name).
• Both: Made up of nucleotides, May contain adenine (A), May contain guanine (G), A nucleic acid, Made of a sugar, phosphate, and nitrogenous base, May contain cytosine (C).
• RNA only: Contains the sugar ribose, Ribonucleic Acid, Single - stranded, May contain uracil (U), Made up of A, U, C & G.
