What Is Protein Expression?

The term “protein expression” is a little foreign to most people. This doesn’t happen regularly in everyday life, so most people probably don’t know what protein expression is or why it’s important. In fact, this term can refer to two specifics, one fact which only adds to the potential for confusion.

Protein expression may relate to the research subject in a protein test or to an actual laboratory technique used to produce the protein. The meaning depends on the context in which it is used. In the case of this article, we will look at the second meaning – namely. Protein expression, which includes laboratory techniques.

The use of protein depends on the actual needs of each cell. DNA is responsible for storing protein images, and RNA for messages is created to convert DNA messages into actual proteins. The word “transcription” is widely used in the world of protein expression and refers to the information passed from DNA to mRNA. Translation, on the other hand, is the actual protein synthesis that results from the mRNA.

In some cases, the transcription and translation processes can be carried out simultaneously, while in other cases it is carried out sequentially, with transcription followed by translation. Transcription and translation can be carried out simultaneously by prokaryotes while they work sequentially on eukaryotes.
