The higher invertebrates are also classified as determinates or indeterminates. this division is based on which developmental function? whether the blastopore ultimately develops into a mouth or an anus whether the process of cell differentiation begins early or late whether the embryonic cells show spiral or radial cleavage whether the coelom forms by splitting the mesoderm or through the pocket of the gut nextreset

One function of the poly-a tail on eukaryotic mrna sequences is to the mrna be transported from the nucleus to the cytoplasm. prokaryotic mrna also has a poly-a tail. choose the best explanation of the prokaryotic poly-a tail. a. prokaryotic poly-a tails have the same functions as eukaryotic poly-a tails, because this process is highly conserved throughout different species. b. prokaryotic poly-a tails aren't important, because prokaryotes don't have nuclei. c. prokaryotic poly-a tails have other functions, because prokaryotes don't have nuclei. d. prokaryotic poly-a tails are composed of a different molecular structure compared with eukaryotic poly-a tails.

One of the purposes of transcription is to produce a sequence of bases that
