What is the structure and function of nucleic acids?
What is the structure and function of nucleic acids?
Nucleic acids, deoxyribonucleic acid (DNA) and ribonucleic acid (RNA), carry genetic information which is read in cells to make the RNA and proteins by which living things function. The well-known structure of the DNA double helix allows this information to be copied and passed on to the next generation.
What are nucleic acids PPT?
Nucleic acids are biopolymers, or small biomolecules, essential to all known forms of life. They are composed of nucleotides, which are monomers made of three components: a 5-carbon sugar, a phosphate group and a nitrogenous base.
What is the main structure of nucleic acids?
Basic structure Nucleic acids are polynucleotides—that is, 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 is structural and functional unit of nucleic acid?
Nucleotides are the structural units of nucleic acids. Answer verified by Toppr.
What are the components of nucleic acids?
nucleic acids:* Macromolecules, the major organic matter of the nuclei of biological cells, made up of nucleotide units, and hydrolysable into certain pyrimidine or purine bases (usually adenine, cytosine, guanine, thymine, uracil), D-ribose or 2-deoxy-D-ribose,and phosphoric acid.
What are two important functions of nucleic acids?
Two main functions of nucleic acids are: (i) DNA is responsible for the transmission of inherent characters from one generation to the next. This process of transmission is called heredity. (ii) Nucleic acids (both DNA and RNA) are responsible for protein synthesis in a cell.
What are the two components of nucleic acids?
Nucleic acids are giant biomolecules made of monomers called nucleotides. Nucleotides have three components: pentose sugar (5-carbon sugar), phosphate group, and nitrogenous base. The nucleic acids are of two major types: natural and synthetic nucleic acids.
What are the responsibilities of nucleic acid?
Nucleic acids are naturally occurring chemical compounds that serve as the primary information-carrying molecules in cells. They play an especially important role in directing protein synthesis. The two main classes of nucleic acids are deoxyribonucleic acid ( DNA) and ribonucleic acid ( RNA ).
What are some facts about nucleic acids?
Nucleic acids are characterized as very large molecules that have distinctively two main parts, usually noted as the double-helix formation. The helix formation that represents a nucleic acid pattern is unique, one that intends to separate one [family’s] biological identification from another.
What are the effects of nucleic acids?

What are the characteristics of a nucleic acid?
Basic Characteristics of Nucleic Acids. Nucleic acids consist of a series of linked nucleotides. Each nucleotide, in turn, is composed of three distinct elements: a five-carbon ribose sugar, a phosphate group and a nitrogenous base.
