- The modern working definition of a gene is a portion (or sequence) of DNA that codes for a known cellular function or process (e.g. the function make melanin molecules). A single 'gene' is most similar to a single 'word' in the English language. The nucleotides (molecules) that make up genes can be seen as 'letters' in the English language. Nucleotides are named according to which of the four nitrogenous bases they contain. The four bases are cytosine, guanine, adenine, and thymine.

Gene A gene is a region of DNA that encodes function. A chromosome consists of a long strand of DNA containing many genes. A human chromosome can have up to 500 million base pairs of DNA with thousands of genes. A gene is a locus (or region) of DNA which is made up of nucleotides and is the molecular unit of heredity. The transmission of genes to an organism's offspring is the basis of the inheritance of phenotypic traits. These genes make up different DNA sequences called genotypes.

What Is Gene Expression? - Regulation, Analysis & Definition Definition of Gene Expression. A gene is a small piece of genetic material written in a code and called DNA. Each gene has within it a set of instructions for making molecules that organisms need to survive. Genes themselves cannot be used by an organism. Instead they must be turned into a gene product. Gene expression is the process by which the information contained within a gene becomes a useful product.

Definitions &Translations Colloquial usage of the term gene may actually refer to an allele: a gene is the basic instruction—a sequence of nucleic acids, while an allele is one variant of that gene. Thus, when the mainstream press refers to having a gene for a specific trait, this is generally inaccurate. In most cases, all people would have a gene for the trait in question, but certain people will have a specific allele of that gene, which results in the trait variant. Further, genes code for proteins, which might result in identifiable traits, but it is the gene, not the trait, which is inherited.
