BiologyCellular processesDNA, genetics and evolutionASOCR Created by: kikaritaeCreated on: 15-04-18 01:21 869472135 Across 1. period of cell division of the cell cycle. Consists of the stages mitosis and cytokinesis. (7, 5) 5. half the normal chromosome number; one chromosome of each type. (7) 8. two identical copies of DNA (a chromosome) held together at a centromere. (10) 9. form of cell division where the nucleus divides twice (meiosis I and meiosis II) resulting in a halving of the chromosome number and producing four haploid cells from one diploid cell. (7) Down 2. proteins that form a complex with DNA called chromatin. (8) 3. third stage of mitosis when chromatids are separated to opposite poles of the cell. (8) 4. growth period of the cell cycle, between cell divisions (mitotic phase). Consists of stages G1, S and G2. (10) 6. fourth stage of mitosis when chromosomes assemble at the poles and the nuclear envelope reforms. (9) 7. uncondensed DNA in a complex with histones. (9) 8. region at which two chromatids are held together. (10)
