What is composed of nucleotides?

What is composed of nucleotides?

A nucleotide is the basic building block of nucleic acids. RNA and DNA are polymers made of long chains of nucleotides. A nucleotide consists of a sugar molecule (either ribose in RNA or deoxyribose in DNA) attached to a phosphate group and a nitrogen-containing base.

What type of nucleic acid is composed of only one strand of nucleotides?

RNA

Is nucleic acid made of nucleotides?

Nucleic acids are polynucleotides—that is, long chainlike molecules composed of a series of nearly identical building blocks called nucleotides. Each nucleic acid contains four of five possible nitrogen-containing bases: adenine (A), guanine (G), cytosine (C), thymine (T), and uracil (U).

What are nucleic acids primarily composed of?

nucleotides

What is this nucleoside phosphate?

CHEBI:25608 – nucleoside phosphate A nucleobase-containing molecular entity that is a nucleoside in which one or more of the sugar hydroxy groups has been converted into a mono- or poly-phosphate. The term includes both nucleotides and non-nucleotide nucleoside phosphates.

Does a nucleoside have a phosphate?

Nucleotides are composed of a nitrogen base (i.e., a purine or pyrimidine), a cyclic pentose, and one or more phosphate groups (Fig. 13-1). The nitrogen base plus the pentose (ribose or deoxyribose) is known as a nucleoside, with addition of phosphate forming a nucleotide.

Is ATP a nucleoside or nucleotide?

It is also a precursor to DNA and RNA, and is used as a coenzyme. From the perspective of biochemistry, ATP is classified as a nucleoside triphosphate, which indicates that it consists of three components: a nitrogenous base (adenine), the sugar ribose, and the triphosphate.

What is the difference between a nucleotide and a nucleoside chegg?

Nucleotides are involved in eukaryotic DNA replication, while nucleosides are used in bacterial DNA replication. A nucleoside with a phosphate ester linked to the sugar is a nucleotide.
