The molecular gene is a sequence of nucleotides in DNA that is transcribed to produce a functional RNA. There are two types of molecular genes: protein-coding genes and non-coding genes. [1] [2] [3] During gene expression (the synthesis of RNA or protein from a gene), DNA is first copied into RNA.
May 21, 2024 · A gene is the basic physical and functional unit of heredity. Genes are made up of DNA and each chromosome contains many genes.
Gene is a peer-reviewed journal of genetics and molecular biology. Find the latest research articles and books on ScienceDirect.com, the leading scientific platform.
4 days ago · Gene, unit of hereditary information that occupies a fixed position on a chromosome. Genes achieve their effects by directing the synthesis of proteins. They are composed of deoxyribonucleic acid (DNA), except in some viruses, which have genes consisting of a closely related compound called ribonucleic acid (RNA).

Oct 30, 2022 · Learn about what genes, DNA, chromosomes, proteins, mutations, and the human genome are and how they relate to each other.
May 14, 2024 · GeneCards®: The Human Gene Database GeneCards is a searchable, integrative database that provides comprehensive, user-friendly information on all annotated and predicted human genes. The knowledgebase automatically integrates gene-centric data from ~150 web sources, including genomic, transcriptomic, proteomic, genetic, clinical and functional information.
Oct 27, 2020 · 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.
5 days ago · 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. Humans have approximately 20,000 protein-coding genes.
How do genes determine the traits of an organism? How do proteins help carry out the instructions encoded in genes? In this article, you will learn about the relationship between genes, proteins, and traits, and how different types of mutations can affect them. This is a foundational topic for understanding inheritance and variation in living things.
