Cells in which epidermal layer are rich in RNA to increase the efficiency of protein synthesis?
A) Stratum corneum
B) Stratum lucidum
C) Stratum spinosum
D) Stratum granulosum

Question

Quizplus · Accepted Answer

The cells in the Stratum spinosum have a high concentration of RNA, which leads to an increased efficiency of protein synthesis. This layer is also where the cells begin the process of keratinization, a process important for the development of skin barrier function. The other layers (Stratum corneum, Stratum lucidum, and Stratum granulosum) do not have the same concentration of RNA in their cells.
