RELEVANT LEARNING OUTCOME:
(a) Describe how the information on DNA is used to synthesise polypeptides. (Description of the processes of transcription, formation of mRNA from pre-mRNA and translation is required.)
Watch the video from 1:18 to 2:11 to observe the process of post-transcriptional modification - 5' capping, 3' polyadenylation and RNA splicing.
💡Process of Post-transcriptional modification
💡Process of Post-transcriptional modification
Take note that the 3 main steps of post-transcriptional modification may not take place in a sequential manner, i.e. they may take place at the same time.
Note: please use the term 'premature mRNA' instead of 'immature mRNA'.
