Chromatid

One of the two identical longitudinal halves of a chrome, which shares a common centromere.

Chromatin

Nuclear material comprising the chromosomes; the DNA- histone complex

Chromatophore

Pigment cell, usually in the dermis.

Chromomeric

Small, stainable thickening arranged linearly along a chromosome

Chromo Last

A plastid containing pigment.

Chromosome

Nucleoprotein structures generally more or less rod- like during nuclear division; the physical sites of nuclear genes arranged in liner order.

Chronic Disease

A disease that persists over a long period of time as compared with the course of an acute disease.

Chile

The turbid liquid products of digestion taken up by the small intestine.

Chymotrypsin

A proteolysis enzyme, produced by the pancreas, that catalysis the hydrolysis of casein and gelatin.

Circadian

Pertaining to a period of 24 hours.

Cirrhosis

A chronic degenerative disease of liver in which the lobes are covered with fibrous tissue, parenchyma degenerates and the lobes are infiltrated with fat.

Citron

A segment of DNA specifying one polypeptide chain in protein synthesis.

Cleavage

The process of repeated mitotic cell divisions in animal zygote.

Clone

A group of cells or organisms derived from single ancestral cell or individual and genetically alike.

Coacervate

An aggregate of colloidal droplets in liquid phase held together by electrostatic forces.

Coagulation

The process of transforming a liquid into a solid, especially of the blood.

Coccyx

The fused caudal vertebrae at the end of the vertebral column.

Cochlea

The part of the ear that converts sound into nerve impulses.

Cocoon

The protective covering around the cluster of eggs or pupa.

Codeine

A narcotic analgesic used to treat mild to moderate pain.

Codon

A sequence of three adjacent nucleotides that codes for one amino acid.

Coenzyme

Low- molecular- weight organic molecule that works together with Apo enzyme to catalyze biological reactions.

Cofactor

A small molecule which may be organic (i.e.. , coenzyme) or inorganic (i.e.. medallion) required by an Apo enzyme in order to function.

Colchicine

A drug that inhibits the polymerization of microtubules, a mitotic poison.

Cold- Blooded

Having the same body temperature as that of the immediate environment.

Collagen

The major structural protein of the extra- cellular matrix.

Colloid

A two – phase system in which particles of one phase are suspended in the second phase.

Colon

The portion of the large intestine extending from the caecum to the rectum.

Coma

A state of a body and mind in the profound unconsciousness.
