Gene - Wikipedia
We define a gene as a DNA sequence that is transcribed. This definition includes genes that do not encode proteins (not all transcripts are messenger RNA). The definition normally excludes regions of the genome that control transcription but are not themselves transcribed.

Gene | Definition, Structure, Expression, & Facts | Britannica
gene, unit of hereditary information that occupies a fixed position (locus) on a chromosome. Genes achieve their effects by directing the synthesis of proteins. In eukaryotes (such as animals, plants, and fungi), genes are contained within the cell nucleus.

What Is a Gene? - Cleveland Clinic
Genes are segments of DNA that give your cells instructions for specific traits or body functions. Different versions of the same gene are called alleles.

Gene
The gene is considered the basic unit of inheritance. Genes are passed from parents to offspring and contain the information needed to specify physical and biological traits.

Gene | Journal | ScienceDirect.com by Elsevier
Gene is dedicated to advancing understanding of genes and genomes, including their regulation, expression, function, and evolution, and their roles in biological processes, phenotypes, and diseases across all biological systems, from prokaryotes to eukaryotes and viruses.

Gene - Structure, Types & Characteristics - GeeksforGeeks
A gene is a basic unit of heredity in biology. It carries instructions encoded in DNA that control the manufacture of particular proteins or useful RNA molecules.

GENE Definition & Meaning - Merriam-Webster
: a part of DNA or sometimes RNA that is usually located on a chromosome and that contains chemical information needed to make a particular protein (as an enzyme) controlling or influencing an inherited bodily trait or activity (as eye color or metabolism) or that influences or controls the activity of another gene or genes

Genes: Function, composition, health impact, and research
Genes are made of deoxyribonucleic acid (DNA), which contains sequences of four nucleotide bases (adenine, cytosine, guanine, and thymine) that act as biological instructions for making proteins.

What is a gene? | Definition of a gene - YourGenome
Our DNA is organised into small sections, called genes. Each gene contains the instructions for making a specific product – usually a protein. Our proteins serve many functions to keep our cells functioning, such as protecting against disease or absorbing nutrients from food.

Gene structure - Wikipedia
A gene is transcribed (copied) from DNA into RNA, which can either be non-coding RNA (ncRNA) with a direct function, or an intermediate messenger RNA (mRNA) that is then translated into protein. Each of these steps is controlled by specific sequence elements, or regions, within the gene.
