MRNA's after translation?

  1. Jun 23, 2012 #1
    What happens to mRNA's after translation. Do they get degraded?

    They can either be rebound by ribosomes and translated again or degraded. Sequences in the untranslated regions of the RNA control the extent to which certain mRNAs get retranslated or degraded.

    the mRNA can be then brought to the ribosome and then with the help of tRNA to help make a protein. Thnk of the mRNA as a recipe to make a protein.

    As Ygggdrasil says, mRNA molecules have a half life determined by the untranslated regions. Every mRNA is different. Some hang around for ages, others a rapidly degraded.
