Are nucleotide monomers or polymers?

Are nucleotide monomers or polymers?

The monomer units of DNA are nucleotides, and the polymer is known as a “polynucleotide.” Each nucleotide consists of a 5-carbon sugar (deoxyribose), a nitrogen containing base attached to the sugar, and a phosphate group.

Are nucleic polymers?

Nucleic acids are linear polymers (chains) of nucleotides. Each nucleotide consists of three components: a purine or pyrimidine nucleobase (sometimes termed nitrogenous base or simply base), a pentose sugar, and a phosphate group which makes the molecule acidic.

Are nucleotides monomers?

The monomers of DNA are called nucleotides. Nucleotides have three components: a base, a sugar (deoxyribose) and a phosphate residue. The four bases are adenine (A), cytosine (C), guanine (G) and thymine (T).

What is the polymer of nucleotide called?

The polymer of nucleotides is called RNA (Ribonucleic acid) and DNA (Deoxyribonucleic acid). Both nucleic acids RNA and DNA consist of Polymer of nucleotides.

Why DNA is a polymer?

DNA is a polymer due to the fact it contains multiple repeating units (monomers). These monomers are known as nucleotides. Multiple nucleotides join together by phosphodiester bonds to form the polymer that is DNA.

Is nucleic acid is an example of polymer?

Nucleic acids are the polymers themselves, the most common of them being DNA and RNA.

Are polypeptides polymers?

Polypeptides (PP) (proteins) are linear polymers of amino acids (H N–CHR–COOH, where R (bonded to the central C) is a variable side chain (“residue”) – there are 20 different natural ones.

Is amino acid a monomer or polymer?

Proteins
Proteins – polymers are known as polypeptides; monomers are amino acids. Nucleic Acids – polymers are DNA and RNA; monomers are nucleotides, which are in turn consist of a nitrogenous base, pentose sugar, and phosphate group.

What is a nucleoside vs nucleotide?

Nucleosides have a nitrogenous base and a five-carbon carbohydrate group, usually a ribose molecule (see Chapter 2). Nucleotides are simply a nucleoside with one or more phosphate groups attached (Figure 4-1). The resulting molecule is found in ribonucleic acid or RNA.

How are the nucleotides of DNA a polymer?

DNA is a polymer. The monomer units of DNA are nucleotides, and the polymer is known as a “polynucleotide.” Each nucleotide consists of a 5-carbon sugar (deoxyribose), a nitrogen containing base attached to the sugar, and a phosphate group.

What makes up the base of a nucleotide?

Explanation: Nucleotides are monomers of nucleic acids, DNA and RNA. A nucleotide is made up of a nitrogenous base (adenine, thymine, guanine, cytosine, or uracil), a phosphate group (PO3−4), and a 5 -carbon sugar.

Which is an example of a polynucleotide molecule?

A single polynucleotide molecule consists of 14 or more monomers of nucleotide in a chain structure. DNA (deoxyribonucleic acid) and RNA (ribonucleic acid) are examples of polynucleotides.

What are the names of the four nucleotides in DNA?

In DNA, there are four nucleotides: adenine, thymine, guanine, and cytosine. Uracil replaces thymine in RNA. Andrey Prokhorov / Getty Images. There are 5 nucleotides that are commonly used in biochemistry and genetics.
