Do you believe that all of our actions can be attributed to the nervous system? Does your memory of an event trigger your responses? Why or why not?

The nervous system is made up of all the nerve cells in your body. It is through the nervous system that we communicate with the outside world and, at the same time, many mechanisms inside our body are controlled. The nervous system takes in information through our senses, processes the information and triggers reactions, such as making your muscles move or causing you to feel pain. For example, if you touch a hot plate, you reflexively pull back your hand and your nerves simultaneously send pain signals to your brain. Metabolic processes are also controlled by the nervous system.

Explanation:

A cell cycle is the chorological order of events that allow them to divide and produce new cells. The cell cycle consists of interphase and M (mitosis). Interphases includes gap1(G1), synthesis (S-phase)  and gap 2 (G2) phase.  

During S-phase or synthesis phase, the cell replicates or duplicates its DNA. Coping of DNA requires lots of energy because replication requires synthesis of lots of nucleotides. At the end of S-phase, the cell have two complete sets of genetic material.

During G2 phase cells both the copies of their DNA are correct and intact. Thus, as per question, during G2 phase it can be observed that the nucleus of a cell contain 6 picograms of DNA.
