The spindle fibers produced by the centrioles are necessary for the division of the chromosome at the time of the anaphase. In case, the centrioles do not perform their task, the genetic material in the cells may not divide equally due to the lack in the separation of the chromosomes. Hence, the problem with the centrioles may lead to the unequal division of the genetic material during the cell division process.
Hence, the correct answer is centrioles.
Bacteria move using a tail like structure called flagellum .

Answer:
Due to convergent evolution/ analogy
Explanation:
Analogy in evolution is the development of similar or analogous structures in distantly related species occupying the same environment. This is because the species have developed similar adaptations, over time, that enables them to survive in their environment.
Answer:
Carries copies of the instructions for assembling proteins: messenger RNA
Makes up the subunits of ribosomes: ribosomal RNA
Carries amino acids and matches them to the coded message for assembling proteins: transfer RNA
sections of an mRNA molecule that are removed: introns
Sections of an mRNA molecule that are not removed, and are joined together to form the completed molecule: exons
