Over a long period of time
Vestigial structures are inherited from ancestors, but have lost much or all of their original function due to different selection pressures acting on the descendant. The hipbones of bottlenose dolphins are vestigial structures. However, as the dolphin lineage adapted to life at sea, this function was lost.
If
CUAGCUCGAUAUCUC is a mRNA sequence then the codes are:
CUA - Leucine
GCU - Alanine
CGA - Arginine
UAU - Tyrosine
CUC – Leucine
<span>This means that the protein synthesized
during the translation is going to have a sequence LeuAlaArgTyrLeu.</span>
The answer is A! Speciation is the right answer
