Question

select all of the following that are components of dna nucleotides.
a. nitrogenous base
b. ribose
c. phosphate group
d. amino acid
e. deoxyribose

Explanation:

• Nitrogenous base: DNA nucleotides have nitrogenous bases (adenine, thymine, cytosine, guanine).
• Ribose: Ribose is part of RNA nucleotides, not DNA. DNA has deoxyribose.
• Phosphate group: DNA nucleotides contain a phosphate group.
• Amino acid: Amino acids are building blocks of proteins, not DNA nucleotides.
• Deoxyribose: DNA nucleotides have deoxyribose as the sugar component.

Answer:

A. Nitrogenous base, C. Phosphate group, E. Deoxyribose
