The four given mutations are inversion mutation, deletion mutation, translocation mutation, and the last one is substitution mutation.
00:20
Now we need to understand what exactly the mechanism of these four mutations are so that we could understand which one can be easily reverted.
00:31
So in case of inversion mutation, there is change in the direction of the chunk of dna that gets replaced within.
00:44
That is if suppose this is the dna sequence, it is 5 dash end and this is 3 dash end and this is the 5 dash end.
00:54
Suppose this chunk of dna is undergoing mutation.
00:58
So since it and this is the part that is undergoing mutation, then this direction is reversed and then it again fits it to the same direction.
01:10
So reversion of such a complex phenomenon of inversion is not likely possible.
01:19
So our first option of inversion mutation is wrong.
01:24
Deletion mutation is the deleting of a chunk of dna or a single nucleotide.
01:32
If it was a single nucleotide deletion, then it would have been called as point mutation.
01:38
But usually deletion mutation explains a chunk of dna or a small fragment of dna...
