The cell membrane of the plant and animal cells help them to maintain homeostasis. It regulates the particles that move in or outside the cell. All cell work in integrity to maintain homeostasis. The organelles also contribute to this process. Vacuole stores food for this, cell membrane acts as a barrier for foreign materials, mitochondria provide the cell with its energy, nucleus controls all the activity, cell wall protects the cell, cytoplasm maintains the integrity of the cell, ribosomes, and endoplasmic reticulum synthesize and transport the proteins required by the cell.

Answer:
False
Explanation:
Primers are the small segments of DNA or RNA. Primers do not cleave DNA at specific regions. It is a function of restriction endonucleases. Primers are required during the process of DNA replication as DNA polymerase cannot start the formation of a new DNA strand without preexisting free 3' OH ends. A primer is formed by a primase enzyme. Primers provide the free 3' OH ends to DNA polymerase which in turn extends them to make the new DNA strands. In PCR, primers serve as the same function for the enzyme of DNA strand formation (Taq polymerase).
