nucleotide structure

A nucleotide is an organic molecule that is the building block of DNA and RNA. ... A nucleotide is made up of three parts: a phosphate group, a 5-carbon sugar, and a nitrogenous base. The four nitrogenous bases in DNA are adenine, cytosine, guanine, and thymine.

What are the 3 parts of a nucleotide?

Each nucleotide, in turn, is made up of a nitrogenous base, a pentose sugar, and a phosphate.

What are the 4 types of nucleotides?

Because there are four naturally occurring nitrogenous bases, there are four different types of DNA nucleotides: adenine (A), thymine (T), guanine (G), and cytosine (C).

What is the basic structure of nucleic acids?

Nucleic acids are long chainlike molecules composed of a series of nearly identical building blocks called nucleotides. Each nucleotide consists of a nitrogen-containing aromatic base attached to a pentose (five-carbon) sugar, which is in turn attached to a phosphate group.

What structures are found in all nucleotides?

All nucleotides are composed of three parts: a five-carbon sugar, a phosphate, and a nitrogen-rich structure called a nitrogenous base. The sugar can be ribose, which is found in ribonucleotides and RNA, or deoxyribose, which is found in deoxyribonucleotides and DNA.

Which best describes the structure of a nucleotide?

A nucleotide is an organic molecule that is the building block of DNA and RNA. ... A nucleotide is made up of three parts: a phosphate group, a 5-carbon sugar, and a nitrogenous base. The four nitrogenous bases in DNA are adenine, cytosine, guanine, and thymine. RNA contains uracil, instead of thymine.

How nucleotide is formed?

A nucleotide is formed from a carbohydrate residue connected to a heterocyclic base by a β-D-glycosidic bond and to a phosphate group at C-5' (compounds containing the phosphate group at C-3' are also known). The molecules derived from nucleotides by removing the phosphate group are the nucleosides.
