AI Thread Summary
After translation, mRNA molecules can either be retranslated by ribosomes or degraded. The untranslated regions of the mRNA play a crucial role in determining their stability and lifespan, influencing how long they persist in the cell. Each mRNA has a unique half-life; some remain stable for extended periods while others are rapidly degraded. This variability affects the efficiency of protein synthesis, as mRNA serves as the template for protein production with the assistance of tRNA.

What happens to mRNA's after translation. Do they get degraded?
 
Biology news on Phys.org
Help?
 
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.
