| chromosomal |
A chromosome (in Greek chroma = colour and soma = body) is, minimally, a very long, continuous piece of DNA, which contains many genes, regulatory elements and other intervening nucleotide sequences. In the chromosomes of eukaryotes, the uncondensed DNA exists in a quasi-ordered structure inside the nucleus, where it wraps around histones (structural proteins, Fig. 1), and where this composite material is called chromatin. ...

| chromatic adaptation |
Color vision is a psychophysical phenomenon that exists only in our minds. A 'red' apple does not emit red light. Rather, it simply absorbs all the frequencies of light shining on it except the frequencies we call red, which are reflected. An apple is perceived to be red only because human can distinguish between different frequencies—and we have language to describe that difference. ...

| chromatid |
A chromatid forms one part of a chromosome after it has coalesced for the process of mitosis or meiosis. Each chromosome consists of two exactly identical ("sister") chromatids. After they have been pulled apart by the mitotic spindle, chromatids are called "chromosomes". Sister chromatids are joined at a point called the centromere. In non-gametic, non-dividing human cells, there are 23 pairs of chromosomes, thus 46 chromosomes. ...

| chromatin |
Chromatin is the substance of a chromosome and consists of a complex of DNA and protein in eukaryotic cells. It can be made visible by staining (thus the name which literaly means coloured material). The nucleic acids are generally in the form of double-stranded DNA. The major proteins involved in chromatin are histone proteins. In a eukaryotic cell, nearly all DNA is found compacted in chromatin. ...

| chromatophore |
Chromatophores or pigment cells are color changing cells used most notably by chameleons as well as cephalopods such as squid and octopuses. A chromatophore is composed of a single chromatophore cell and numerous muscle, nerve, glial and sheath cells. These cells are contractile and contain vesicles that contain three different liquid pigments. To change their color the cells distort their form or size stretching or contracting their outer covering thus changing its translucency or opacity. ...
