The nucleotides forming DNA molecules consist of which three parts?
A
A phosphate group, a sugar molecule, and a lipid molecule
B
A sugar molecule, a lipid molecule, and a nitrogenous base
C
A phosphate group, a lipid molecule, and a nitrogenous base
D
A phosphate group, a sugar molecule, and a nitrogenous base
Verified step by step guidance1
Understand that nucleotides are the building blocks of DNA, and each nucleotide is composed of three distinct parts.
Identify the three components of a nucleotide: a phosphate group, a sugar molecule, and a nitrogenous base.
Recognize that the sugar molecule in DNA is deoxyribose, which is a five-carbon sugar.
Note that the nitrogenous base can be one of four types: adenine (A), thymine (T), cytosine (C), or guanine (G).
Confirm that the correct combination of components forming a DNA nucleotide is a phosphate group, a sugar molecule, and a nitrogenous base.
