Question

select all of the characteristics of dna to test your understanding of its chemical structure.

check all that apply

deoxyribose sugar

ribose sugar

phosphate group

nitrogenous bases

Explanation:

Identify the components of a DNA nucleotide

DNA (Deoxyribonucleic acid) is composed of nucleotides, each containing a 5-carbon sugar, a phosphate group, and a nitrogenous base.

Evaluate each option against DNA chemical structure

• Deoxyribose sugar: This is the 5-carbon sugar found in DNA (RNA contains ribose). This is correct.
• Ribose sugar: This is found in RNA, not DNA. This is incorrect.
• Phosphate group: This forms the acidic, negatively charged backbone of DNA. This is correct.
• Nitrogenous bases: DNA contains the nitrogenous bases adenine (A), thymine (T), cytosine (C), and guanine (G). This is correct.

Answer:

• Deoxyribose sugar (Correct answer)
• Ribose sugar
• Phosphate group (Correct answer)
• Nitrogenous bases (Correct answer)
