Hello students.
00:01
So in this question, they have given a dna sequence and they are asking you to find the coding dna, non -coding dna, the mrna sequence and the protein sequence of this particular dna molecule.
00:14
So if we observe with respect to the coding dna, all we can see is that the coding dna is the one that is in the 3 prime to 5 prime direction, right? so in this case, which one is the one that has 3 prime to 5 prime direction? it is this particular sequence, right? the below sequence is the one that is the coding dna in this case.
00:37
The non -coding dna if we have to see, it is in 5 prime to 3 -prime direction.
00:41
Okay? so the 5 -prime to 3 -prime direction is the top part or the top dna strand that you see here.
00:49
This is the one that is the non -coding dna strand.
00:53
Now if we have to see the mrna sequence, it is formed from the coding dna, right? so it is complementary to this particular dna.
01:01
So in this case, if we observe the answer or the sequence of the mrna, we observe it is 5 prime u, g, a, c, a, u -g, g, g, g, g, u, a -c -a -c -c -a -c -a -c -g -g -g -3 prime end, right? so in this case, how did i get this equation or rather how did i get this sequence? basically, if we observe, the mr -n -a sequence is nothing but the complementary to the dna sequence just that instead of thymine there is uracil that is present...
