Gene expression - Wikipedia
WEBGene expression is the process by which information from a gene is used in the synthesis of a functional gene product that enables it to produce end products, proteins or non-coding RNA, and ultimately affect a phenotype.
Intro to gene expression (central dogma) - Khan Academy
WEBInformation from a gene is used to build a functional product in a process called gene expression. A gene that encodes a polypeptide is expressed in two steps. In this process, information flows from DNA → RNA → protein, a directional relationship known as the central dogma of molecular biology.

WEB6 days ago · Gene expression is the process by which the information encoded in a gene is turned into a function. This mostly occurs via the transcription of RNA molecules that code for proteins or non-coding RNA molecules that serve other functions. Gene expression be thought of as an “on/off switch” to control when and where RNA …
Gene expression and regulation | AP®︎/College Biology - Khan Academy
WEBDNA helps make us who we are, but how exactly does it work? In this unit, we'll examine the nitty gritty of replication, transcription, and translation, and learn how seemingly small mutations can have a big impact on our lives.
Gene Expression - The Definitive Guide | Biology Dictionary
WEBNov 11, 2020 · Definition. Gene expression in eukaryotes (cells with DNA inside a nucleus) and prokaryotes (single-celled organisms without a nucleus) describes how certain proteins are manufactured in specific cells according to a DNA-based recipe. Certain cell components can read gene sequences to synthesize amino acid chains (polypeptides) …
