What three components make up a nucleotide?
a phosphate, a deoxyribose, and a nitrogenous base
an enzyme, a deoxyribose, and a nitrogenous base
a deoxyribose, a phosphate, and an enzyme
a phosphate, an enzyme, and a nitrogenous base
a phosphate, a deoxyribose, and a nitrogenous base
The correct answer is: a phosphate, a deoxyribose, and a nitrogenous base.
The correct answer is: a phosphate, a deoxyribose, and a nitrogenous base.
To arrive at this answer, you can break down the question and look at the individual components that make up a nucleotide.
1. Phosphate: A nucleotide consists of a phosphate group, which is a molecule that contains phosphorus and oxygen. This phosphate group is attached to the 5' carbon of the sugar molecule.
2. Deoxyribose: The second component is a deoxyribose, which is a sugar molecule. Deoxyribose is a modified form of ribose that lacks an oxygen atom on the second carbon.
3. Nitrogenous base: The final component of a nucleotide is a nitrogenous base. There are four types of nitrogenous bases in DNA: adenine (A), thymine (T), guanine (G), and cytosine (C).
Together, these three components (phosphate, deoxyribose, and a nitrogenous base) make up a nucleotide, the building block of DNA.
