Gene vs. DNA
The main difference between gene and DNA is that gene is small stretches of DNA that determines a specific trait, whereas DNA is a chemical structure that stores the genetic information.
Key Differences
Gene shares only genetic information because it contains only small threads of DNA and carries only genetic information, but DNA shares all the material, not only genetic information.
Gene is the small stretches of DNA that determines a specific trait or encodes for different proteins, whereas DNA is a chemical structure that stores the genetic information of living organisms.
Gene determines only a specific trait of a living one; on the other hand, DNA controls many functions such as gene regulation.
Gene is made up of DNA or RNA; on the contrary, DNA is made up of simpler monomer units called nucleotides.
Gene is a region or a specific nucleotide on DNA strands, on the flip side, DNA is double-stranded molecule where each strand is complementary and further coiled to form a double-helix structure.
A gene is present on a chromosome, whereas DNA is present inside the nucleus and nucleoid of the cell.
Structurally gene is only small stretches of DNA; on the contrary, DNA is a long chain of polynucleotides.

Gene and DNA Definitions
Gene
A hereditary unit consisting of a sequence of DNA that occupies a specific location on a chromosome and is transcribed into an RNA molecule that may function directly or be translated into an amino acid chain. Genes undergo mutation when their DNA sequences change.
Dna
A nucleic acid that carries the genetic information in cells and some viruses, consisting of two long chains of nucleotides twisted into a double helix and joined by hydrogen bonds between the complementary bases adenine and thymine or cytosine and guanine. DNA sequences are replicated by the cell prior to cell division and may include genes, intergenic spacers, and regions that bind to regulatory proteins.
Gene
(genetics) A theoretical unit of heredity of living organisms; a gene may take several values and in principle predetermines a precise trait of an organism's form (phenotype), such as hair color.
Dna
Alternative form of DNA
Gene
(molecular biology) A segment of DNA or RNA from a cell's or an organism's genome, that may take several forms and thus parameterizes a phenomenon, in general the structure of a protein; locus.
A change in a gene is reflected in the protein or RNA molecule that it codes for.
Dna
Abbreviation for deoxyribonucleic acid; - more commonly used than the full name. See also RNA.
Gene
(genetics) a segment of DNA that is involved in producing a polypeptide chain; it can include regions preceding and following the coding DNA as well as introns between the exons; it is considered a unit of heredity;
Genes were formerly called factors
Dna
(biochemistry) a long linear polymer found in the nucleus of a cell and formed from nucleotides and shaped like a double helix; associated with the transmission of genetic information;
DNA is the king of molecules

Gene called the central dogma of molecular biology, whereas DNA’s complete set in an organism is called genome. The studies about gene started a long time ago, but the studies about DNA recently started.
What is Gene?
Gene is the small stretches of DNA that determines a specific trait or encodes for different proteins. Gene determines only a specific trait of a living one. Structurally gene is only small stretches of DNA. A gene is a region or a specific nucleotide sequence present on the DNA strand. Gene has an amino acid sequence of specific proteins of the body. About thirty thousand genes are present inside a single cell/DNA. Gene is considered as the hereditary unit since the studies show them as the basic unit of transfer of genetic information from parents. Gene is present on chromosomes, and each chromosome has a definite character that will show only a particular trait. Gene shares only genetic information because it contains only small threads of DNA and carries only genetic information. Gene is composed of either DNA or RNA. During gene expression, DNA first copied into RNA and then RNA change into proteins directly or as a template for a protein to perform a function. This transmission of the gene into an offspring is the basis of inheritance. The studies about gene started in the earlier centuries.
What is DNA?
DNA is a chemical structure that stores the genetic information of living organisms. It is genetic material of all the living organisms. It is present inside the nucleus of the cell or nucleoid. DNA stores all the information of a living one other than genetic information for a long-term, which is essential for the development and reproduction. DNA is made up of simpler monomer units called nucleotides. These monomers consist of three groups: pentose sugar, a nitrogenous base, and a phosphate group. Nitrogenous base and phosphate group used to attach to the pentose sugar. Four different nitrogenous bases identified in DNA are cytosine(C), thymine(T), adenine(A), and guanine(G). These nitrogenous bases arranged in different orders for store genetic information. The order of the nucleotide sequence on the sugar-phosphate backbone recognized as genes. DNA is a double-stranded molecule where each strand is complementary and further coiled to form a double-helix structure. This double helix structure forms the B-form geometry. Large double-stranded DNA molecule having 3.2 billion base pairs and 25,000 genes.
