Across
  1. 1. It is a structural layer surrounding some types of cells, situated outside the cell membrane.
  2. 3. It is the first phase of mitosis.
  3. 6. The daughter cells are identical to the parent as well as to each other.
  4. 8. It is technically the final stage of mitosis.
  5. 10. It is homologous chromosomes separate leading to daughter cells that are not genetically identical.
  6. 13. It is the part of a chromosome that links a pair of sister chromatids.
  7. 15. An organized profile of a person's chromosomes.
  8. 16. It contains the diploid chromosome number and it produces through mitosis.
  9. 17. It is divided into two domains, bacteria and archaea.
  10. 20. Cells with one set.
  11. 21. If it was made up of DNA, it acts as instructions to make molecules called proteins.
  12. 23. It forms a protein structure that divides the genetic material in a cell.
  13. 25. Any cell or organism that possesses a clearly defined nucleus.
  14. 26. It is a variant form of a gene.
  15. 27. It is found only in animal cells and it is used during cell reproduction.
  16. 28. It is the third phase of mitosis.
Down
  1. 1. It is the basic structural, functional, and biological unit of all known living organisms.
  2. 2. It is a process of programmed cell death that occurs in multicellular organisms.
  3. 4. It is made up of long chains of amino acids.
  4. 5. It links amino acids together in the order specified by messenger RNA molecules.
  5. 7. They are made of protein and one molecule of DNA, which contains an organism's genetic instructions, passed from parents.
  6. 9. Cells with two sets.
  7. 11. Contain the haploid chromosome number and produce through meiosis.
  8. 12. It is found in all living things.
  9. 14. It is encoded either in DNA or for many types of virus in RNA.
  10. 18. It is one of several structures with specialized functions, suspended in the cytoplasm of a eukaryotic cell.
  11. 19. It can be divided by mitosis to produce more of that.
  12. 22. A specialized structure occurring in most cells and separated from the rest of the cell by a double layer, the nuclear membrane.
  13. 24. It is the phase of the cell cycle in which a typical cell spends most of its life.
