|
in a eukaryotic cell, one of the structures in the nucleus that are made up of dna and protein

chromosome
|
|
the exchange of genetic material between homologous chromosomes during meiosis

crossing over
|
|
a phase of mitosis or meiosis, during which a nuclear membrane forms around each set of new chromosomes

|
a period between two meiotic divisions during wich the cell grows, copies its dna, and synthesizes
