  1. 2. The process involoved in the production of new cells genetically identical with the original cell
  2. 4. Specific complement of chromosomes present in a cell or an individual
  3. 7. The death of cells which occurs as a normal and controlled part of an organism's growth or development
  4. 11. Any number of organised or specialized structures living within a cell
  5. 13. The process of cell division that results in the production of new cells, each containing half the number of chromosomes of the original cell
  6. 14. Specific segment of DNA carrying an instruction encoded in its base sequence for a specific protein product
  7. 16. contains four bases, A G C T, they form the major component of chromosomes and contain coded genetic instructions
  8. 19. The different forms of a particular gene
  9. 20. Cells of the body other than germline cells
  10. 21. In the mitotic cell cycle, period of cell growth and DNA synthesis
  11. 23. Having one copy of each specific chromosome
  12. 24. Rod-shaped organelles, they are important for cell division and the formation of spindle
  13. 26. Cell or organism with a membrane-bound nucleus
  14. 27. The total number of the genes present in a cell or an organism
  15. 28. Built of amino acidsub-units and linked by peptide bonds to form a chain
Down
  1. 1. Organisms or cells having two copies of each specific chromosome, having a paired set of chromosomes
  2. 2. Mitosis stage where chromosomes align around the equator of a spindle (form between cells during mitosis, to which chromosomes become attached)
  3. 3. Stage of mitosis in which new nuclear membranes form around the separated groups of chromosomes
  4. 5. Organelle containing RNA that is the major site of protein production in cells
  5. 6. The control centre of the cell where DNA, the genetic information of your body is kept
  6. 8. Clusters of microtubes, composed of protein that grow out from the centrioles at opposite ends of the spindle
  7. 9. Cells or organisms without membrane-bound nucleus
  8. 10. Cells involved in reproduction
  9. 12. Structure composed of DNA and protein. Visible in cells during mitosis
  10. 15. Smallest structural and functional unit of an organism
  11. 17. located outside of the plasma membrane in plant cells
  12. 18. The position where the chromatids are held together in a chromosome
  13. 22. Stage of mitosis in which the chromosomes contract and become visable, the nuclear membrane begins to disintegrate and the spindle forms
  14. 25. Eggs of a female or sperm of a male
