Question

Accepted Answer

To solve this, we analyze each characteristic based on DNA (D), RNA (R), or both (B) knowledge:

### 1. Made up of nucleotides
Both DNA and RNA are nucleic acids made of nucleotides.
**Answer:** B

### 2. May contain cytosine
Cytosine is in both DNA (C pairs with G) and RNA (C pairs with G).
**Answer:** B

### 3. Made of sugar, phosphate, nitrogenous bases
Both DNA (deoxyribose) and RNA (ribose) have sugar, phosphate, and nitrogenous bases.
**Answer:** B

### 4. A nucleic acid
Both DNA (deoxyribonucleic acid) and RNA (ribonucleic acid) are nucleic acids.
**Answer:** B

### 5. Made up of A, C, T, and G
DNA has adenine (A), cytosine (C), thymine (T), guanine (G). RNA has U instead of T.
**Answer:** D

### 6. May contain adenine
Adenine is in both DNA (A - T) and RNA (A - U).
**Answer:** B

### 7. Ribonucleic acid
RNA is ribonucleic acid; DNA is deoxyribonucleic acid.
**Answer:** R

### 8. Contains the sugar deoxyribose
DNA has deoxyribose; RNA has ribose.
**Answer:** D

### 9. DNA double - helix (image)
The double - helix structure is unique to DNA.
**Answer:** D

### 10. Single - stranded
RNA is single - stranded; DNA is double - stranded.
**Answer:** R

### 11. May contain uracil
RNA has uracil (U) instead of thymine; DNA has thymine.
**Answer:** R

### 12. Deoxyribonucleic acid
DNA is deoxyribonucleic acid.
**Answer:** D

### 13. May contain guanine
Guanine is in both DNA (G - C) and RNA (G - C).
**Answer:** B

### 14. Contains the sugar ribose
RNA has ribose; DNA has deoxyribose.
**Answer:** R

### 15. Made up of A, U, C, and G
RNA has adenine (A), uracil (U), cytosine (C), guanine (G). DNA has T instead of U.
**Answer:** R

### 16. May contain thymine
Thymine is only in DNA (A - T); RNA has U.
**Answer:** D

### 17. Double - stranded
DNA is double - stranded; RNA is single - stranded.
**Answer:** D

### 18. RNA structure (image, single - stranded)
The single - stranded structure is RNA.
**Answer:** R
