A chromosome is a DNA molecule with part or all of the genetic material (genome) of an organism. Prokaryotes usually have one single circular chromosome, whereas most eukaryotes are diploid, like humans. Chromosomes in eukaryotes are composed of chromatin fiber. Chromatin fiber is made of nucleosomes. A nucleosome is a histone octamer with part of a longer DNA strand attached to and wrapped around it.
Diploid human cells have 2 sets of 23 chromosomes for a total of 46 chromosomes: By Regina Bailey. Definition: A haploid cell is a cell that contains one complete set of chromosomes.Gametes are haploid cells that are produced by meiosis.Examples: The haploid number is the number of chromosomes within the nucleus of a cell that constitutes one complete chromosomal set. This number is commonly abbreviated as n, where n stands for the number of chromosomes.ametes are haploid cells that are produced by meiosis.
