Gene expression is the process by which specific genes are activated to produce a required protein. The process is made up of the transcription and translation of DNA sequences.
Every cell in a multicellular organism contains a complete set of chromosomeThe structure made of DNA that codes for all the characteristics of an organism. with every geneThe basic unit of genetic material inherited from our parents. A gene is a section of DNA which controls part of a cell's chemistry - particularly protein production. needed to make every protein that that organism will ever make.
However, in any particular cell, only a very small fraction of these genes are ever expressed.
Each cell is specialised to carry out a certain task and will only need to express certain genes.
Gene expression is the process by which specific genes are activated to produce a required protein.
The gene expression process is made up of the transcription and translation of DNA sequences. This involves RNA.
