Inversion of DNA sequences within chromosomes is a common process in evolution. The following gene arrangements in a particular

chromosome are found in four different species.
1st sequence STUVWX
2nd sequence UVXTSW
3rd sequence UVWSTX
4th sequence SWVUTX
1. Assuming that the arrangement in 1 is the original arrangement, in what evolutionary order did the four species arise, such that there is only one inversion between each species. (Place 1st sequence first in your ordering.)

Answer:

2, 3, 4, 1

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 .
