We know that transcription is the first step in gene expression. In the transcription process, information from a gene is used to build a functional product such as a protein. The primary goal of transcription is to produce an RNA copy of a gene's from a DNA sequence.
For a protein-coding gene, the RNA copy, or transcript, carries that information that is needed to build a polypeptide.
Eukaryotic transcripts need to go through some processing steps before starting of translation into proteins.
