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)
made up of nucleotides
may contain adenine (a)
may contain guanine (g)
dna
deoxyribonucleic acid
double stranded
made up of a, c, t & g
both
a nucleic acid
made of a sugar, phosphate, and nitrogenous base
may contain cytosine (c)
rna
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 statement based on DNA and RNA structure:

1. "Contains the sugar deoxyribose"

• DNA has deoxyribose; RNA has ribose. So only DNA.

2. "May contain thymine (T)"

• Thymine is unique to DNA (RNA has uracil instead). So only DNA.

3. DNA double - helix diagram

• DNA is double - stranded; RNA is single - stranded. So only DNA.

4. "Made up of nucleotides"

• Both DNA and RNA are nucleic acids made of nucleotides. So BOTH.

5. "May contain adenine (A)"

• Adenine is a nitrogenous base in both DNA (A - T pair) and RNA (A - U pair). So BOTH.

6. "May contain guanine (G)"

• Guanine is in both DNA (G - C pair) and RNA (G - C pair). So BOTH.

Sorting:

• Only DNA:
• Contains the sugar deoxyribose
• May contain thymine (T)
• DNA double - helix diagram
• BOTH:
• Made up of nucleotides
• May contain adenine (A)
• May contain guanine (G)
• Only RNA (already in the diagram: Contains the sugar ribose, Ribonucleic Acid, Single stranded, May contain uracil (U), Made up of A, U, C & G)

If we were to place the left - side cards:

• "Contains the sugar deoxyribose" → DNA circle.
• "May contain thymine (T)" → DNA circle.
• DNA double - helix diagram → DNA circle.
• "Made up of nucleotides" → BOTH section.
• "May contain adenine (A)" → BOTH section.
• "May contain guanine (G)" → BOTH section.
