Cuts heal when growth factors in the dermal layer of the skin signal cells in the epidermal layer to divide. This process takes time and coordination as shown in the figure below. In the past 10-20 years, researchers have conducted many in-vitro and animal studies that have showed promise using growth factors to facilitate healing in impaired wounds, bone regeneration, and nerve regeneration. Researchers hope that the application of growth factors may be used clinically to enhance the wound healing process. The cellular process that enables the cells to grow and develop into tissue is —

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.
