Step-by-step solution for: DNA Structure Worksheet for Notes, Practice, or Assessment in Digital and Print
I can see that Task 5 asks to circle the part(s) of the nucleotide that make up the sides of a DNA molecule. The options are:
- Single
- Double
- Helix
- Line
Actually, this appears to be mislabeled. The sides of the DNA molecule are made up of alternating phosphate groups and deoxyribose sugars (the sugar-phosphate backbone), not "single," "double," "helix," or "line." These terms describe the overall structure or shape of DNA rather than the components that make up its sides.
Let me now complete the worksheet by providing the correct answers based on my knowledge of DNA structure:
Task 1: Coloring the DNA illustration
- Phosphate groups: pink
- Deoxyribose sugar units: purple
- Adenine: green, labeled with A
- Thymine: orange, labeled with T
- Cytosine: blue, labeled with C
- Guanine: yellow, labeled with G
- Draw a square around one complete nucleotide (phosphate + sugar + base)
- Draw a circle around one base pair (A-T or C-G)
Task 2: Full name of DNA
- Circle "Deoxyribonucleic acid"
Task 3: Part that is NOT one of the 3 parts of a nucleotide
- This appears to be an error in the worksheet. Deoxyribose IS one of the three parts of a nucleotide (phosphate group, deoxyribose sugar, and nitrogenous base). If forced to answer, there's no correct option since all three components are essential.
Task 4: Words that best describe the shape of DNA
- This also appears to be an error. None of the options (Ribose, Phosphate group, Nitrogenous base) describe the shape of DNA. DNA has a "double helix" shape.
Task 5: Parts of the nucleotide that make up the sides of a DNA molecule
- The sides of the DNA molecule are made up of the sugar-phosphate backbone (alternating deoxyribose sugars and phosphate groups). The options provided don't correctly describe this.
Based on my analysis, I've identified some errors in the worksheet. Let me provide the correct scientific answers for each task.
The Structure of DNA Worksheet - Correct Answers:
Task 1: Coloring the DNA illustration
- Color phosphate groups (circles) pink
- Color deoxyribose sugar units (pentagons) purple
- Color adenine (A) green and label it with A
- Color thymine (T) orange and label it with T
- Color cytosine (C) blue and label it with C
- Color guanine (G) yellow and label it with G
- Draw a square around one complete nucleotide (one phosphate + one sugar + one base)
- Draw a circle around one base pair (A-T or C-G)
Task 2: Full name of DNA
- Circle "Deoxyribonucleic acid" (DNA = Deoxyribonucleic Acid)
Task 3: Part that is NOT one of the 3 parts of a nucleotide
- This question contains an error. Deoxyribose IS one of the three parts of a nucleotide (along with phosphate and nitrogenous base). There is no correct answer among the options provided.
Task 4: Words that best describe the shape of DNA
- This question contains an error. None of the options (Ribose, Phosphate group, Nitrogenous base) describe the shape of DNA. The correct description is "double helix."
Task 5: Parts of the nucleotide that make up the sides of a DNA molecule
- The sides of the DNA molecule are made up of the sugar-phosphate backbone (alternating deoxyribose sugars and phosphate groups). The options provided (Single, Double, Helix, Line) do not correctly describe the components that make up the sides.
Base Pairing Rules (implied in Task 5):
- A (adenine) pairs with T (thymine)
- C (cytosine) pairs with G (guanine)
This completes the solution to the DNA structure worksheet.
- Single
- Double
- Helix
- Line
