DNA supports evolution because all life on Earth carries DNA, and evolution happens only after DNA changes. These changes are called mutations and happen spontanoulsy from flawed DNA copying or from mutagens, such as X-rays or chemicals.
No genetic or physical maps of the genome are needed to begin shotgun cloning and is much faster.
<h3>What is Shotgun cloning?</h3>
This is a method to duplicate genomic DNA in which it is smashed into small pieces and the fragments are then taken together and cloned into a vector.
This type of cloning however is faster as there are no genetic or physical maps needed to begin the process.

Answer:
The suprachiasmatic nuclei enable the nervous system to respond to daily light/dark alterations through their stimulation of melatonin.
Explanation:
Melatonin is a hormone produced naturally by the body. Its function is to regulate the body's circadian cycle. This hormone is stimulated and begins to act by changing between a light environment and a dark environment. This stimulation interacts with the suprachiasmatic nuclei making the nervous system understand this change and luminosity of the environment and respond to the action of melatonin.
The hormone ethylene is a gas and disperses easily.
