How is tRNA made?

Published in tRNA Synthesis 1 min read

tRNA (transfer RNA) is made through a process called transcription, facilitated by RNA polymerase III in eukaryotic cells.

Here's a breakdown of the tRNA creation process:

  1. Transcription:

    • A special protein reads the DNA code.
    • This protein creates an RNA copy, known as pre-tRNA.
    • RNA polymerase III is the specific enzyme responsible for this transcription step in eukaryotic cells.
  2. Processing:

    • The pre-tRNA undergoes processing after it exits the nucleus.

In summary, tRNA production involves transcribing the DNA sequence into pre-tRNA by RNA polymerase III, followed by processing steps outside the nucleus to form the mature tRNA molecule.
