Final answer:
Terminally differentiated cells are non-dividing cells committed to specific functions and can still produce RNAs. They are cleared by apoptosis at the end of their lifespan and replaced by stem cells. In abnormal cases, if these cells avoid apoptosis, it can result in uncontrolled division and potential tumor formation.
Step-by-step explanation:
Cells that are terminally differentiated: d. can still produce RNAs. Terminally differentiated cells have reached their final specialized state and often have limited ability to undergo cell division. While they may have reduced or no capacity for further cell division, they can still maintain certain cellular functions, including the production of RNAs. Even though they may not actively replicate or divide, terminally differentiated cells can transcribe and translate specific genes necessary for their specialized functions. This ongoing gene expression allows them to carry out their dedicated roles in tissues and contribute to the overall function and homeostasis of the organism.
