Cell Division Flashcards
Cell continuity
All cells develop from pre-existing cells
Chromosomes
Coiled threads of protein and DNA that become visible in the nucleus at cell division
Gene
Section of DNA that contains the instructions to make a protein
Homologous pair
Two chromosomes of similar size with the same sequence of genes
Mitosis
Form of nuclear division in which one nucleus divides to form two nuclei
Cell cycle
Changes in a cell between cell divisions
Interphase
Period when the cell is not dividing
Cancer
Group of disorders in which certain cells lose their ability to control the rate of mitosis and the number of times it occurs
Meiosis
Form of nuclear division in which the four daughter nuclei contain half the chromosome number of the parent nucleus
Centromere
Point at which chromosomes are attached
