A chromosome has generally 8 parts; Centromere or primary constriction or kinetochore, chromatids, chromatin, secondary constriction, telomere, chromomere, chromonema, and matrix. Centromere or Kinetochore: It is the primary constriction at the center to which the chromatids or spindle fibers are attached.

Diagram of Chromosome Structure. A chromosome is a physically discrete portion of the genome, which carries many individual genes. Eukaryotic chromosomes are composed of chromatin, which is a mixture of DNA and protein.The protein, primarily histones, acts as a scaffold organizing the structure of the DNA, which is a long string (polymer) of nucleotides (adenine, cytosine, guanine, and thymine.

Chromosomes are a key part of the process that ensures DNA is accurately copied and distributed in the vast majority of cell divisions. Still, mistakes do occur on rare occasions. Changes in the number or structure of chromosomes in new cells may lead to serious problems.

A karyotype is the number and appearance of chromosomes. To obtain a view of an individual's karyotype, cytologists photograph the chromosomes and then cut and paste each chromosome into a chart, or karyogram, also known as an ideogram. In a given species, chromosomes can be identified by their number, size, centromere position, and banding.

1. INTRODUCTION Studies initiated during the last quarter of the nineteenth century gradually revealed the key roles of chromosomes in storing and transmitting hereditary information and in generating genetic variation. The most frequent method to study chromosome organization and behavior had been optical microscopy.

Chromosome number. Different species have different numbers of chromosomes. For example, humans are diploid (2n) and have 46 chromosomes in their normal body cells. These 46 chromosomes are organized into 23 pairs: 22 pairs of autosomes and 1 pair of sex chromosomes. The sex cells of a human are haploid (n), containing only one homologous.

What are Chromosomes?
Chromosome Definition. A chromosome is a string of DNA wrapped around associated proteins that give the connected nucleic acid bases a structure. During interphase of the cell cycle, the chromosome exists in a loose structure, so proteins can be translated from the DNA and the DNA can be replicated. During mitosis and meiosis, the chromosome.
Chromosome vs Chromatid
Introduction When a cell divides, one of its main jobs is to make sure that each of the two new cells gets a full, perfect copy of genetic material. Mistakes during copying, or unequal division of the genetic material between cells, can lead to cells that are unhealthy or dysfunctional (and may lead to diseases such as cancer).
