Definition Of A Nucleic Acid

Any of a class of large molecules that are polymers of nucleotides and are found in all living organisms and viruses. The nucleic acids are vital biopolymers found in all living things where they function to encode transfer and express genes.

Nucleic Acid Definition Function Structure Types Britannica

Basically nucleic acids can be subdivided into two types.

Definition of a nucleic acid. The principal nucleic acids DNA and RNA are the carriers of hereditary information and control the synthesis of proteins. Nucleic acids include DNA and RNA. These large molecules are called nucleic acids because they were first identified inside the nucleus of cells however they are also found in mitochondria and chloroplasts as well as bacteria and viruses.

Deoxyribonucleic acid better known as DNA and ribonucleic acid better known as RNA. Nucleotides are composed of a nitrogenous base a five-carbon sugar and a phosphate group. Nucleic acid definition any of a group of long linear macromolecules either DNA or various types of RNA that carry genetic information directing all cellular functions.

Sugars There are only two types of sugar present in nucleic acids ribose which. A nucleotide is made of a nitrogenous base sugar with five carbon atoms and a phosphate group. Nucleic acids are macromolecules that store genetic information and enable protein production.

They are involved in the preservation replication and expression of hereditary information in every living cell. Nucleotides are organic molecules consisting of a nucleoside and a phosphateThey serve as monomeric units of the nucleic acid polymers deoxyribonucleic acid DNA and ribonucleic acid RNA both of which are essential biomolecules within all life-forms on Earth. They play an especially important role in directing protein synthesis.

Nucleic acids are large molecules where genetic information is stored. Definition of nucleic acid. A type of acid that exists in all living cells.

It creates DNA and RNA which store the information needed by cells to create proteins. This information is stored in multiple sets of three nucleotides known as codons. Nucleic acid Noun Any acidic chainlike biological macromolecule consisting of multiply repeat units of phosphoric acid sugar and purine and pyrimidine bases.

Any of various complex organic acids such as DNA or RNA that are composed of nucleotide chains Examples of nucleic acid in a Sentence Recent Examples on the Web Every day millions of Americans immune systems are reprogrammed by sophisticated strands of frozen nucleic acid. Nū-klēik asid A family of macromolecules found in the chromosomes nucleoli mitochondria and cytoplasm of all cells and in viruses. Both DNA and RNA have been shown to consist of three groups of molecules.

The two main classes of nucleic acids. Medical Dictionary for the Health Professions and Nursing Farlex 2012. There are two types of nucleic acids.

These molecules are composed of long strands of nucleotides. The nucleic acids are made of nucleotides. Nucleotides are obtained in the diet and are also synthesized from common nutrients by the liver.

A nucleic acid is a chain of nucleotides which stores genetic information in biological systems. Nucleic acids were so named because they were first found in the nucleus of cells but they have since been discovered also. Nucleic acids are naturally occurring chemical compounds that serve as the primary information-carrying molecules in cells.

Deoxy-ribonucleic acid DNA and ribonucleic acid RNA. In complexes with proteins they are called nucleoproteins. Wiktionary 000 0 votesRate this definition.

One of the family of large molecules which includes deoxyribonucleic acid DNA and ribonucleic acid RNA. A type of acid that exists in all living.
