Question

complete the table to compare the structure of dna and rna.
table with columns: (blank), dna, rna; rows:

• is typically a single - stranded molecule
• is typically a double - stranded molecule
• contains the 5 - carbon sugar deoxyribose
• contains the 5 - carbon sugar ribose; each cell has a checkbox

Explanation:

To solve this, we recall the structural differences between DNA and RNA:

Row 1: "is typically a single - stranded molecule"

• RNA is typically single - stranded. So we check the box under RNA.
• DNA is typically double - stranded, so we leave the box under DNA unchecked.

Row 2: "is typically a double - stranded molecule"

• DNA is typically double - stranded (forms a double helix). So we check the box under DNA.
• RNA is typically single - stranded, so we leave the box under RNA unchecked.

Row 3: "contains the 5 - carbon sugar deoxyribose"

• The name "DNA" stands for Deoxyribonucleic Acid, and it contains deoxyribose. So we check the box under DNA.
• RNA contains ribose, not deoxyribose, so we leave the box under RNA unchecked.

Row 4: "contains the 5 - carbon sugar ribose"

• The name "RNA" stands for Ribonucleic Acid, and it contains ribose. So we check the box under RNA.
• DNA contains deoxyribose, not ribose, so we leave the box under DNA unchecked.

Filled Table (in text form):

	DNA	RNA
is typically a double - stranded molecule	☑	☐
contains the 5 - carbon sugar deoxyribose	☑	☐
contains the 5 - carbon sugar ribose	☐	☑

(Note: In the actual table, you would mark the appropriate checkboxes as per the above.)
