Answer:
d. None of these
Explanation:
Probably the identical sequence found in both species<em> </em>is an<em> ultraconserved sequence. </em>
An <u>ultraconserved element</u> is a particular DNI sequence that remains exactly the same through evolution, with almost no modification, and that is shared by at least two completely different species.
These ultraconserved DNI portions seem to be highly essential for life. However, their function could not be determined yet. Most of them do not codify for proteins, but they could play a significant role in gene regulation.
It is suggested that these sequences are so significant for life that only a small change would compromise the organism´s aptitude.
B.
The other options all tell you the type of nucleic acid it is.
