Answer:
<h2>The Tri-Chromtic theory</h2>
Explanation:
The Tri-chromatic theory is based on the assumption that the three classes of cone receptors sub serve the colour vision. This theory dates back to 18th century and was popular during the first half of 20th century and was often used against the opponent processes theory. It was also known as Young-Helmholtz theory of colour vision, according to this theory there are three receptors in the retina that are responsible for the perception of colour. These receptors have different sensitivity level. Blues ones are the most sensitive and the red ones the least. But to perceive the colour needs the interaction between at least two photo receptors. Then the three colours are combined to form any colour in the visible spectrum.

DNA is often coiled around histone proteins, the combination of DNA & protein is called chromatin
Inside the nucleus of each mobile, the DNA molecule is packaged into thread-like structures called chromosomes. each chromosome is made up of DNA tightly coiled generally round proteins known as histones that help its shape.
The proteins that bind to the DNA to form eucaryotic chromosomes are traditionally divided into two general classes: histones and nonhistone chromosomal proteins. The complex of both classes of protein with the nuclear DNA of eucaryotic cells is known as chromatin.
The blended loop of DNA and protein is known as a nucleosome. next, the nucleosomes are packaged right into a thread, which is every now and then defined as "beads on a string". The stop end result is a fiber called chromatin. Now the chromatin fiber is coiled into a shape referred to as a "solenoid".
