Answer to Question #189906 in Molecular Biology for Misbah

Question

A terminator acts as a termination signal in the process of transcription, whereas termination of translation is brought about by a stop codon. How the terminator and stop codon differ from each other with regards to ending the process in which they are involved? 

Answer 1

A stop codon is a codon (nucleotide triplet within messenger RNA) that signals the termination of the translation process of the current protein. A terminator is a special sequence of nucleotides in DNA that marks the end of a gene. It signals RNA polymerase to release the newly made RNA molecule, which then departs from the gene.
