in a eukaryotic cell, one of the structures in the nucleus that are made up of DNA and protein; in a prokaryotic cell, the main ring of DNA
a type of protein molecule found in the chromosomes of eukaryotic cells but not prokaryotic cells
the region of the chromosome that holds the two sister chromatids together during mitosis
the material that makes up both mitotic and interphase chromosomes; a complex of proteins and DNA strands that are loosely coiled such that translation and transcription can occur
chromosomes that have the same sequence of genes, that have the same structured, and that pair during meisosis
a micrograph of the array of chromosomes visible in a cell during metaphase; a graphical display that shows and individual's chromosomes arranged in homologous pairs and in order of diminishing size
a form of asexual reproduction in single-celled organisms by which one cell divides into two cells of the same size
in eukaryotic cells, a process of cell division that forms two new nuclei, each of which has the same number of chromosomes
reproduction that does not involve the union of gametes and in which a single parent produces offspring that are genetically identical to the parent.
a process in cell division during which the number of chromosomes decreases to half the original number by two divisions of the nucleus, which results in the production of sex cells
a haploid reproductive cell that unites with another haploid reproductive cell to form a zygote
a period between two mitotic or meiotic divisions during which the cell grows, copies its DNA, and synthesizes proteins
the division of the cytoplasm of a cell; cytokinesis follows the division of the cell's nucleus by mitosis or meiosis
the first stage of mitosis and meiosis in cell division; characterized by the condensation of the chromosomes and the dissolution of the nuclear envelope
one of the microtubules that extend across a dividing eukaryotic cell; assists in the movement of chromosomes
one of the stages of mitosis and meiosis, during which all of the chromosomes move to the cell's equator
the final stage of mitosis or meiosis, during which a nuclear membrane forms around each set of new chromosomes
