Gene - Wikipedia
网页A gene is a DNA sequence that codes for a diffusible product. This product may be protein (as is the case in the majority of genes) or may be RNA (as is the case of genes that code for tRNA and rRNA). The crucial feature is that the product diffuses away from its site of synthesis to act elsewhere.

What is a gene? - MedlinePlus
网页2024年5月21日 · A gene is the basic physical and functional unit of heredity. Genes are made up of DNA. Some genes act as instructions to make molecules called proteins, which are needed for the body to function. However, many genes do not code for proteins, instead they help control other genes.

Gene
网页2024年9月19日 · Definition. 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. Most genes code for specific proteins, or segments of proteins, which have differing functions within the body.
Gene - Definition and Examples - Biology Dictionary
网页2020年10月27日 · A gene is an extremely specific sequence of nucleotide monomers that has the ability to completely or partially control the expression of one or more traits in every type of living organism. Genes are formed from deoxyribonucleic acid (DNA) and, in the case of some viruses, ribonucleic acid (RNA) polymers.
What Are Genes, DNA, and Chromosomes? - Verywell Health
网页2024年8月22日 · Genes are the basic units that determine the traits that we inherit from our parents. They contain coded information found in nearly every cell of the human body. Our genes are made up of DNA, a molecule with this coded information. Hundreds to thousands of genes are found on each chromosome inside our cells.
Gene - Definition and Examples - Biology Online Dictionary
网页2023年9月8日 · A gene is defined as the fundamental, physical, and functional unit of heredity since a gene is comprised of nucleotides (on a specific site on a chromosome) that is responsible for the physical and heritable characteristics or phenotype of an organism.
Gene Expression | Learn Science at Scitable - Nature
