Where does the helicase start unzipping

Biology

answer: It begins at a site called the origin of replication, and it creates a replication fork by separating the two sides of the parental DNA. This 'unzipping' of the molecules will expose the nitrogenous bases of the nucleic acid chain so that new nucleotides can be added to create the daughter strand.

Interneuron, skeletal muscle, somatic receptor, afferent nerve fiber, and efferent nerve fiber.

The action potential from skin receptors is sent by nerves in this type of reflex system.

Sensory neurons advance the motion to the Central Nervous System (CNS).

The efferent neuron or motor neuron causes changes at the effector, which are the skeletal muscles, for adequate integration and responsiveness.

Reflex action refers to the full series of actions. The reflex arc is the name of the route.

Somatic receptor followed by afferent nerve fiber, interneurons, efferent nerve fiber, and skeletal muscle constitutes the proper order.
