Expression

Expression is a term used in various fields, including biology, genetics, and psychology, to denote the process by which information from a gene is used to create a functional product, such as a protein, or the manifestation of a trait or behavior.

Biology and Genetics

In the context of biology and genetics, expression refers to the process by which a gene's DNA sequence is converted into the structures and functions of a cell. Genes are expressed through the processes of transcription and translation, which produce RNA and proteins, respectively.

Transcription

Transcription is the first step in gene expression. It involves copying a gene's DNA sequence to make an RNA molecule. This RNA molecule, known as messenger RNA (mRNA), serves as a template for building a protein.

Translation

Translation is the second step in gene expression. It involves decoding the mRNA molecule to build a protein. This process takes place in the cell's ribosomes.

Psychology

In psychology, expression refers to the process of making known one's thoughts, feelings, and emotions. This can be done through various means, including verbal communication, body language, and artistic mediums.
