Bodies within the nucleus made in DNA and proteins called the histones
Globular protein that assist in DNA packaging in eukaryotes.
Bodies of tightly coiled chromatin; visible during cell division. Two of them bound at a centromere make a CHROMOSOME.
Area where the chromatids of a chromosome are attached
DNA and protein that makes up chromosomes
Chromosomes that determine the sex of an individual
Any chromosome that is not a sex chromosome
Chromosomes that have the same sequence of genes and the same structure
A display of the chromosome pairs of a cell arranged by size and shape.
(genetics) an organism or cell having two sets of chromosomes or twice the haploid number
(genetics) an organism or cell having only one complete set of chromosomes
A form of asexual reproduction in single-celled organisms by which one cell divides into two cells of the same size
The other three products of meiosis that eventually degenerate.
A haploid cell such as an egg or sperm.
Protein structures which move the chromosomes during cell division.
A double membrane across the midline of a dividing plant cell, between which the new cell wall forms during cytokinesis.
Process in which homologous chromosomes exchange portions of their chromatids during meiosis.
