This is so I know it, too.

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 DNA
a type of protein molecule found in the chromosomes of eukaryotic cells but not prokaryotic cells
one of the two strands of a chromosome that become visible during meiosis or mitosis
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
one of the pair of chromosomes that determine the sex of an individual
any chromosome that is not a sex chromosome
chromosomes that have the same sequence of genes, that have the same structure, and that pair during meiosis
a micrograph of the array of chromosomes visible in a cell during metaphase; a graphical display that shows an individual's chromosomes arranged in homologous pairs and in order of diminishing size`
a cell that contains two haploid sets of chromosomes
describes a cell, nucleus, or organism that has only one set of unpaired chromosomes
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
a haploid reproductive cell that unites with another haploid reproduction cell to form a zygote
a period between two mitotic or meiotic divisions buring which the cell grows, copies its DNA, and dynthsizes proteins
the division of the cytoplasm of a cell; _________ 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
a phase of mitosis and meiosis in which the chromosomes separate
the final stage of mitosis or meiosis, during which a nuclear membrane forms around each set of new chromosomes
the precursor of a new plant cell wall that forms during cell division and divides a cell into two
the pairing of homologous chromosomes during meiosis
the four chromatid in a pair of homologous chromosomes that come together as a result of synapsis during meiosis
the exchange of genetic material between homologous chromosomes during meiosis; can result in genetic mutation
the regrouping of genes in an offspring that results in a genetic makeup that is different from that of the parents
the random distribution of the pairs of genes on different chromosomes to the gametes
the process by which male gametes form
the production, growth, and maturation of an egg, or ovum
short-lived products of the formation of gametes by meiosis
reproduction in which gametes from two parents unite
