Top Questions on Transcription
The process of copying the genetic information from one strand of DNA into RNA is termed as transcription. The principle of complementarity of bases governs the process of transcription, also except that uracil comes in place of thymine.

Notes on Transcription
Concepts Used:
Transcription
The very first stage of gene expression is the procedure of transcription. In this procedure, mRNA is the place where the genetic information is stored which later aids in encoding a protein. In this process, the DNA strand acts as a guide in the making of mRNA. Despite the fact that there is one exception which is adenine base pairs with uracil instead of thymine.
Transcription Unit:
The transcription unit is a set of freshly combined RNA molecules that have been transcribed from DNA. The cause is to encode at least one gene. A protein that has been encoded or encrypted with a DNA transcription unit may have a coding sequence. Transcription has a lower copying fidelity rate when differentiated from DNA replication.
The Stages of Transcription:
The procedure of transcription is enzymatically catalyzed into three steps:
- Initiation
- Elongation
- Termination
