Concurrent transcription, translation and mRNA degradation is the simultaneous occurrence of three processes in a cell, namely transcription, translation and mRNA degradation.
Transcription involves the synthesis of mRNA from a DNA template by RNA polymerase, which includes initiation, elongation and termination. During transcription, the DNA molecule unwinds and a complementary RNA molecule is synthesized from one of the strands.
Translation involves the synthesis of proteins from the mRNA template in ribosomes. During translation, the mRNA molecule undergoes a process called translation initiation, where it binds to a ribosome and begins translation. Elongation and termination steps then follow, leading to the synthesis of a protein from the mRNA template.
mRNA degradation involves the breakdown and disposal of mRNA molecules that are no longer required by the cell. This process is regulated to prevent the accumulation of unnecessary mRNAs in the cell. mRNA degradation can occur at different stages of transcription or translation, depending on the specific mRNA and cellular conditions.
Concurrent transcription, translation, and mRNA degradation can occur in a bacterial cell, where transcription and translation occur in the same compartment, the cytoplasm. In eukaryotes, transcription occurs in the nucleus and then mRNA is transported to the cytoplasm where it undergoes translation and eventual degradation. The coordination of these processes is essential for the efficient functioning of the cell.
