Capitolo 7, Problema 17
A nucleotide is made of:
a. A five-carbon sugar
b. Phosphate
c. A nitrogenous base
d. All of the above
Guida verificata passo dopo passo1
Understand that a nucleotide is the basic building block of nucleic acids like DNA and RNA.
Recall that each nucleotide consists of three main components: a five-carbon sugar, a phosphate group, and a nitrogenous base.
The five-carbon sugar can be either deoxyribose (in DNA) or ribose (in RNA).
The phosphate group links the sugar of one nucleotide to the sugar of the next nucleotide, forming the backbone of the nucleic acid strand.
The nitrogenous base (adenine, thymine, cytosine, guanine, or uracil) is attached to the sugar and is responsible for base pairing and encoding genetic information.

Structure of a Nucleotide
A nucleotide is the basic building block of nucleic acids like DNA and RNA. It consists of three components: a five-carbon sugar, a phosphate group, and a nitrogenous base. These components link together to form the backbone and informational units of genetic material.

Detailed DNA Structure
Five-Carbon Sugar
The five-carbon sugar in nucleotides is either ribose (in RNA) or deoxyribose (in DNA). This sugar forms the central part of the nucleotide, connecting to both the phosphate group and the nitrogenous base, and helps establish the nucleotide’s identity and function.

Nitrogenous Bases
Nitrogenous bases are organic molecules that contain nitrogen and act as the information carriers in nucleotides. They are classified into purines (adenine and guanine) and pyrimidines (cytosine, thymine in DNA, and uracil in RNA), and their sequence encodes genetic information.
