Do nucleic acids contain amino and carboxyl groups?

Do nucleic acids contain amino and carboxyl groups?

A common functional group found in amino acids is the amino group −NH2 (Figure 2). Other commonly occurring functional groups include carboxyl groups (−COOH) in amino acids, methyl groups (−CH3), and phosphate groups (–PO3) in nucleic acids.

What organic molecule contains amino and carboxyl group?

Proteins
Proteins are polymers made up of nitrogen-containing monomers called amino acids. An amino acid is a molecule composed of an amino group and a carboxyl group, together with a variable side chain.

What organic molecules combine to make nucleic acids?

DNA and RNA are made up of monomers known as nucleotides. The nucleotides combine with each other to form a polynucleotide: DNA or RNA. Each nucleotide is made up of three components: a nitrogenous base.

What are the small molecules that are linked together to make nucleic acids called?

Nucleic acids are macromolecules, which means they are molecules composed of many smaller molecular units. Thes units are called nucleotides, and they are chemically linked to one another in a chain. In DNA, the nucleotides are referred to in shorthand as A, C, T, and G.

What is the relationship between proteins and nucleic acids?

Protein and Nucleic Acid Relationship The major relationship between the two has to do with protein production — DNA contains the information that a cell uses, with the help of RNA, to make protein.

What makes up the monomeric unit of nucleic acids?

The monomeric unit of nucleic acids is known as nucleotide and is composed of a nitrogenous base, pentose sugar, and phosphate. The nucleotides are linked by a 3’ and 5’ phosphodiester bond.

How are nucleotides linked together to form monomers?

Nucleic Acid Monomers. Nucleotides are linked together to form polynucleotide chains. They are joined to one another by covalent bonds between the phosphate of one and the sugar of another. These linkages are called phosphodiester linkages. Phosphodiester linkages form the sugar-phosphate backbone of both DNA and RNA.

What are the different types of nucleic acids?

Key Takeaways: Nucleic Acids 1 Nucleic acids are macromolecules that store genetic information and enable protein production. 2 Nucleic acids include DNA and RNA. 3 Nucleotides are composed of a nitrogenous base, a five-carbon sugar, and a phosphate group.

Which is a nitrogenous base in a nucleic acid?

Nucleic acids are composed of nucleotide monomers linked together. Nucleotides have three parts: Nitrogenous bases include purine molecules (adenine and guanine) and pyrimidine molecules (cytosine, thymine, and uracil.) In DNA, the five-carbon sugar is deoxyribose, while ribose is the pentose sugar in RNA.
