Cells

1. the smallest unit of life that can replicate independently
2. when a cell has one set of chromosomes
6. a speacialized structrure within a living cell
9. third stage of mitosis; separation of sister chromatids
11. first stage of mitosis
12. a sequence of DNA which codes for a type of molecule with a particular function
13. genetic material of a living organism
14. programmed cell death
15. carries genetic information and forms chromosomes
18. final stage of mitosis; sister chromatids are at opposite poles
19. the point where a pair of chromosomes connect
21. cell division where daughter cells are identical to parent cell
22. the longest phase of the cell cycle
24. cell division that produces four daughter cells, each with half the chromosomes of the parent cell
25. any cell of an organism excluding reproductive cells
26. macromolecules made of chains of amino acid residue
27. each alternative form of a gene

1. outermost protective layer of a plant cell
3. the appearance and number of chromosomes in a cell
4. fibre protein structures that divide genetic material in a cell
5. the organelle containing the cell's genetic material in eukaryotes
7. an organism in which the genetic material is formed as chromosomes found in the nucleus
8. a thread-like structure containing genetic information in the form of genes
10. unicellular organism that lacks membrane-bound organelles
13. cells produced by meiosis in the gonads (ovaries, testes)
16. organelle that assists in mitosis and the production of spindle fibres
17. matured male or female germline cells
20. a protein creating organelle
23. when a cell has two sets of chromosomes
