Final answer:
Excessive amounts of DNA can impair cellular functions and increase cellular energy consumption. However, it does not decrease genetic mutations.
Step-by-step explanation:
Excessive amounts of nucleic acids, also known as DNA, can have several effects on cellular functions. One of the effects is impaired cellular functions. When there is an excess of DNA, it can disrupt the normal flow of reactions involved in protein synthesis and cellular regulation. This disruption can lead to damage to the cell.
Additionally, excessive DNA can also lead to increased cellular energy. The cell may need to allocate more resources to deal with the excess DNA, which can result in higher energy consumption.
It is important to note that excessive DNA does not lead to decreased genetic mutations. In fact, an accumulation of DNA mutations can occur over time and increase the risk of genetic abnormalities and diseases.
