Which of the following is not a function of muscle tissue?

Muscle tissue has several key functions that are essential for the overall operation of the body. Among these functions, facilitating movement is central, as muscles contract to produce motion. Additionally, muscle tissue contributes to maintaining body posture and generating heat, which is crucial for regulating body temperature.

However, one of the options listed—storing genetic information—does not align with the functions of muscle tissue. Genetic information is stored within the cells of the nucleus in the form of DNA, not within muscle tissue itself. This function is primarily associated with cells such as those found in the brain and skin, where DNA plays a critical role in cellular processes, reproduction, and heredity.

Thus, the correct choice highlights the distinction between muscle tissue's actual roles in bodily functions and the functions that do not pertain to it.
