Transcription vs. Reverse Transcription: What's the Difference?

Edited by Huma Saeed || By Sumera Saeed || Updated on October 28, 2023
Transcription converts DNA into RNA, while reverse transcription synthesizes DNA from an RNA template.

Key Differences

Transcription is a fundamental cellular process where a specific segment of DNA serves as a template to synthesize complementary RNA molecules. In contrast, reverse transcription refers to the synthesis of a DNA strand using an RNA molecule as the template.

In transcription, the enzyme RNA polymerase reads the DNA template and builds the corresponding RNA molecule. Meanwhile, in reverse transcription, the enzyme reverse transcriptase converts RNA back into a complementary DNA strand.

Transcription is an essential step in gene expression, enabling the genetic information in DNA to be transformed into a format suitable for protein synthesis. Reverse transcription, on the other hand, is vital in the life cycles of retroviruses, allowing them to integrate into the host genome.

The end product of transcription is an RNA molecule, which can be messenger RNA (mRNA), transfer RNA (tRNA), or ribosomal RNA (rRNA) among others. The result of reverse transcription is a DNA molecule, often leading to the formation of a provirus in retroviral infections.

While transcription plays a crucial role in nearly all cells, ensuring genes are expressed as proteins when needed, reverse transcription is more specialized, being primarily associated with retroviruses and certain cellular processes, like the formation of telomeres.
