MCAT Question of the DayWhich layer of the epidermis is characterized by a low rate of mitosis and a high concentration of keratin? A. Stratum basale B. Stratum spinosum C. Stratum corneum D. Stratum lucidum - correct answer Correct Answer: C. Stratum corneum If a layer of epidermis has a low rate of mitosis, this indicates that the cells in this layer are not dividing very frequently. Likewise the presence of keratin, signals that the layer of epidermis must have a waterproofing functi...
