Read this article to get information about the chemical composition of Chromosomes! The major chemical components of the chromosome are DNA, RNA (nucleic acids), and proteins (histones and nonhistones). There is, in addition, calcium, which seems to be associated with the DNA (Barton, 1951, Mazia, 1954a). Calcium is important in binding sections of the chromosome together (Mazia, Steffensen, 1955). DNA, [...]
This article provides information about the Fine or Ultrastructure of Chromosome! [I] Chromosome is the multistranded body: The smallest unit of chromosome (by electron microscopy) is the fibril, which is 100 A thick. This fibril contains two DNA double helixes, separated by a space about 25 A across, and the associated protein. The next largest unit of the chromosome is [...]
Read this article to get information on chromosomes, its number, shape, and size! Number: The number of chromosomes in a given species is usually constant containing diploid number of chromosomes in their somatic cells and haploid (gametic or reduced) number of chromosomes in their sex cells (sperms and ova). The number of chromosomes is variable from one to several hundreds [...]
