Nerve poisons, or nerve gases are organic chemicals that interfere with the mechanism by which nerves transfer messages to organs. The interference is as a result of the blocking of acetylcholinesterase, and enzyme that catalyzes the breakdown of acetycholine, a neurotransmitter. Therefore, a poison that blocks acetylcholine receptors on dendrites may reduce or decrease the binding of acetycholine to its receptors on the postsynaptic membrane.
Answer:
It exhibits traits and metabolic instructions of the cell.
Explanation:
A DNA strand is a thin long molecule, with an average width of just around two nanometers. The remarkable thinness of the DNA strands allows them to be bundled very tightly fitted inside cells. Once DNA has been replicated adequately during the process of cell division, it is further wrapped together under a mechanism known as supercoiling. A non-condensed DNA is further condensed during supercoiling using a special protein known as a histone. A part of DNA packed around a large cluster of histones is called a nucleosome. Additional condensation leads to a chromosome or the most compact type of DNA that fits into the nucleus. It is also worth noting that this wrapping does not merely align DNA into a cell, but serves other objectives such as protecting DNA, thus ensuring metabolic instructions to the cell.
