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 .
I think it lived about 50 million years ago because I know for sure it has to be greater than 10,000 because that is the minimum. It states that fossils are dated more than 10,000 years. Don’t take my word yet, wait for other replies,I could be wrong
Answer:
i would answer C
