DNA deoxyribonucleic acid is the genomic material in cells that contains the genetic information used in the development and functioning of all known living organisms. DNA, along with RNA and proteins, is one of the three major macromolecules that are essential for life. Within the nucleus of eukaryotic cells, DNA is organized into structures called chromosomes. The complete set of chromosomes in a cell makes up its genome; the human genome has approximately 3 billion base pairs of DNA arranged into 46 chromosomes. DNA consists of two long polymers of simple units called nucleotides, with backbones made of sugars and phosphate groups joined by ester bonds.
DNA is a deoxyribonucleic acid and is a hereditary material in all living organism. It is located in the nucleus of cell which is known as nuclear DNA. Do you know who had reported first time nucleic acids in - Friedrich Miescher from nuclei of pus cells. How Genetics define the hereditary characteristics of human? It occurs inside the nucleus of cell and some cell organelles but it plants it is present in mitochondria and plant cell. It has two nucleotide strands consisting of phosphate group, five carbon sugar stable deoxyribose 2 and four nitrogen bases. It is single stranded consisting of phosphate group, five carbon sugar less stable ribose and four nitrogen base.
DNA stands for Deoxyribonucleic Acid. The sugar portion of DNA is 2-Deoxyribose. The sugar portion of RNA is Ribose….. Save my name and email in this browser for the next time I comment.
DNA has four nitrogen bases adenine, thymine, cytosine, and guanine and for RNA instead of thymine, it has uracil. Another thing is that DNA is missing an oxygen. DNA is a double-stranded molecule with a long chain of nucleotides while RNA is only single-stranded. In most of its biological roles and has a shorter chain of nucleotides after transcription and splicing, only exons remain in RNA. DNA exists mainly in a double helix form while RNA will take on many different shapes and sizes such as the 'hair pin formation'. DNA is used to carry an organism's genetic information while RNA takes on many different roles, for instance, RNA can act as an enzyme such as ribozyme. DNA is a long polymer with deoxyriboses and phosphate backbone.
This is a comparison of the differences between DNA versus RNA, including a quick summary and a detailed table of the differences. This table summarizes the key points:. Also, RNA is found in prokaryotes , which are believed to precede eukaryotes.
RNA , abbreviation of ribonucleic acid , complex compound of high molecular weight that functions in cellular protein synthesis and replaces DNA deoxyribonucleic acid as a carrier of genetic codes in some viruses. RNA consists of ribose nucleotides nitrogenous bases appended to a ribose sugar attached by phosphodiester bonds, forming strands of varying lengths. The ribose sugar of RNA is a cyclical structure consisting of five carbons and one oxygen. The structure of the RNA molecule was described by R. Holley in

Nucleic acids are the biopolymers , or large biomolecules , essential to all known forms of life. They are composed of nucleotides , which are the monomers made of three components: a 5-carbon sugar , a phosphate group and a nitrogenous base. If the sugar is a compound ribose , the polymer is RNA ribonucleic acid ; if the sugar is derived from ribose as deoxyribose , the polymer is DNA deoxyribonucleic 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.
DNA is the genetic material found in all living organisms, ranging from single-celled bacteria to multicellular mammals. It is found in the nucleus of eukaryotes and in the chloroplasts and mitochondria. In prokaryotes, the DNA is not enclosed in a membranous envelope, but rather free-floating within the cytoplasm.
