CENTRAL DOGMA :: PART 6

TRANSCRIPTION

-          The process of formation of mRNA from DNA is called transcription.

-          mRNA can be made from both RNA and DNA with the help of different enzymes.

-          DNA dependent RNA polymerase makes a RNA copy of the required part of the DNA.

-          This takes place in the nucleus and the mRNA comes into the cytoplasm to synthesize protein.

                    
-          Before synthesis of proteins and after formation of mRNA, the produced mRNA undergoes a chain of changes called post transcriptional modifications.
