chromosomes

Chromosomes - Chromosomes (chroma = colour, soma = body) are tiny thread-like structures found in the nucleus of a cell. In a non-dividing cell they appear as a chromatin network while during cell division they become condensed to form short and thick chromosomes. ..

Waldeyer is credited with the discovery of chromosomes in the year 1888 within the nucleus. He observed them as darkly stained bodies. However, it was the American William Sutton who noticed the similarities between the behaviour of the mendelian factors or genes and that of the ..

There are chromosomes which are extremely large compared to normal chromosomes. Such chromosomes, called giant chromosomes occur in some animal cells. Two types of giant chromosomes are kn..

Centromere is the primary constriction in the chromatid of a chromosome where the spindle tubules become attached during cell division. A chromosome generally has only one centromere and such a chromosome is described as monocentric. Sometimes two centromeres may..

The number of chromosomes is fixed for a given species. It varies from a minimum of two to several hundreds in different species of plants and animals. All individuals of a given species show the same chromosome number in all their body cells. The number of chromosomes..

Eukaryotic Chromosome - The eukaryotic cells show a varied number of chromosomes. It is presumed to be the result of breaking up of a single long chromosome into several short units, in the course of evolution, to accommodate the increase in the amount of genetic infor..
