The list contains both characteristics and components of some nucleic acids.
1. Single stranded
2. Deoxyribose
3. Ribose
4. Uracil
5. Thymine
6. Adenine
7. Phosphate group
8. Hydrogen bonds
Which of these are characteristics and components of DNA
1, 2, 3, 5, and 7
2, 5, 6, 7, and 8
1, 3, 4, 7, and 8
2, 4, 5, 6, and 7
The correct answer is:
2, 5, 7, and 8
DNA is double stranded, so it is not single stranded (1). It contains deoxyribose as its sugar component (2), thymine as one of its four nitrogenous bases (5), and a phosphate group (7). Additionally, DNA is held together by hydrogen bonds (8). Ribose (3) and uracil (4) are characteristics and components of RNA, not DNA. Adenine (6) is a component of both DNA and RNA.
