Across
  1. 2. the diploid cell that results from fertilization
  2. 3. using gametes to make a new organism
  3. 5. sets of 3 bases on an mRNA strand
  4. 7. smallest subunits of a protein
  5. 10. small section of DNA that codes for a specific trait
  6. 12. the joining of gametes, when two haploid cells become a diploid cell
  7. 14. a type of reproduction where cells do mitosis to reproduce and the new organism is identical to the parent organism
  8. 15. chromosomes which code for the same trait
  9. 16. the phase of the cell cycle where the cell membrane pinches off and the single parent cell becomes two daughter cells
  10. 17. the process of copying the entire DNA in a cell to make a second strand
  11. 18. pollen, ovules, sperm or egg cells, cells with half the number of chromosomes
  12. 20. a group of things that are planned, designed, and built to work together
  13. 21. process of using the information in DNA to make a protein
  14. 22. nucleic acid whose bases are adenine, cytosine, guanine, and uracil
  15. 23. the phase of the cell cycle that includes prophase, metaphase, anaphase, and telophase with the goal of organizing cell organelles and DNA to make 2 complete cells
Down
  1. 1. Interphase, mitosis, and cytokinesis
  2. 4. process of copying DNA into an mRNA strand
  3. 6. the phase of the cell cycle where a cell grows, does normal cellular functions, and copies its DNA
  4. 8. set of 3 bases on a tRNA molecule
  5. 9. smallest subunit of nucleic acid that contains a sugar, phosphate, and base
  6. 11. the process of making gamete cells which reduce the number of chromosomes in the daughter cells from the parent cell
  7. 13. Idea that if one part of the system is removed, the whole system doesn't work
  8. 19. the processes of turning a mRNA strand into a chain of amino acids called a protein
