In transcription, the DNA sequence of a gene is transcribed (copied out) to make an RNA molecule.Transcription is the first step in gene expression. It involves copying a gene's DNA sequence to make an RNA molecule.In biology, transcription is the process of copying out the DNA sequence of a gene in the similar alphabet of RNA.
During transcription DNA is used as a template to make RNA. RNA then leaves the nucleus and goes to a ribosome in the cytoplasm, where translation occurs. Translation reads the genetic code in mRNA and makes a protein.
