And this hairpin structure contains this stem section and the loop section. So the hairpin is also known as the stem loop structure. And as our RNA molecule forms this structure, because the bonding is no longer strong enough, it will dissociate from that hairpin. And so now we form that RNA molecule. And that RNA molecule can be modified in different ways if it is found inside eukaryotic cells. Now, another way by which we can terminate the process of transcription is by using a special protein known as row.
