tRNA

Post by bethanyulm » Thu May 04, 2006 5:06 pm

Hello! hope everyone is doing well on finals or if you are out then congrats!! but i need help on this question

Do genes for tRNAs have promoters and start codons?

How are tRNA and rRNA molecules coded for? Wouldn't they require a start/stop codon?

Start and Stop codons are for the traduction...

you don't need one since you don't translate them into proteins...

How do they know when to start/stop transcription from the DNA to the RNA? Are promoters, basal factors, etc. still involved with rRNA and tRNA as in mRNA? I apologize if these questions sound basic, but I'm still a general biology student.
