Answer (1)

Answer: 1. DNA is a biomolecule that forms a double helix structure in living organisms.- Agree: This is a fundamental fact about DNA. It's a complex molecule composed of two strands that twist around each other to form a double helix. 2. DNA is responsible for determining the specific characteristics of an organism.- Agree: DNA contains the genetic code that dictates an organism's traits, from eye color to height and even susceptibility to certain diseases. 3. Each nucleotide of DNA contains sugar, a phosphate group, and one nitrogenous base.- Agree: A nucleotide is the building block of DNA. It consists of a sugar molecule (deoxyribose), a phosphate group, and one of four nitrogenous bases: adenine (A), guanine (G), cytosine (C), or thymine (T). 4. Nucleotides are the basic building blocks of DNA.- Agree: As mentioned above, nucleotides are the monomers (building blocks) that link together to form the long chains of DNA. 5. The four bases of a nucleotide are the adenine, uracil, guanine, thymine.- Disagree: This statement is incorrect. While adenine, guanine, and thymine are correct, uracil is found in RNA, not DNA. The correct base for DNA is cytosine (C). In summary:- Statements 1, 2, 3, and 4 are all correct and accurately describe key features of DNA.- Statement 5 is incorrect.
