Transcription

Transcription is the biological process where the genetic code stored in DNA is copied into a messenger RNA (mRNA) molecule. This occurs in the cell nucleus, where an enzyme called RNA polymerase reads the DNA sequence and synthesizes a complementary RNA strand. The mRNA then carries this genetic information from the nucleus to the cell's protein-making structures called ribosomes. Essentially, transcription is how the cell converts the information in DNA into a form that can be used to produce proteins, which are essential for different functions and structures in the body.
