Explanation:
Inversion of DNA sequences refers to the rearrangement of the sequences where a segment is reversed end to end.
For instance in order for the gene of species to have the sequence STUVWX
The order of evolution will be
- sequence UVXTSW will be the first sequence
When XTSW segment is inverted WSTX
- sequence UVWSTX will be the result of the inversion.
section UVWS is inverted to SWVU
- sequence SWVUTX is formed.
when WVUT undergoes inversion to TUVW
- It becomes the original arrangement of STUVWX .
