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:
-
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.
-
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.
