Expression

From WikiMD's Wellness Encyclopedia

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[edit | edit source]

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[edit | edit source]

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[edit | edit source]

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[edit | edit source]

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.
