Across
  1. 3. A change in genotype & phenotype due to the assimilation of external DNA by a cell
  2. 7. Likelihood that a particular event will occur
  3. 8. The principle that bonds in DNA can form only between A&T and C&G
  4. 11. The process of separating DNA from the rest of the cell
  5. 15. Group of 3 bases on a tRNA molecule that are complementary to an mRNA codon
  6. 16. Organism that contains genes from other organisms
  7. 18. Cross between parent with different traits
  8. 19. A process by which a cell, cell product, or organism is copied from an original source
  9. 20. Process of selecting a few organisms with desired traits to serve as parents for the next generation
  10. 21. Repeating nucleotide at the ends of DNA molecules that do not form genes & help prevent the loss of genes
  11. 22. RNA that associates with proteins to form ribosomes
  12. 23. Specific region of a gene where RNA polymerase can bind & begin transcription
  13. 27. Separation of alleles during gamete formation
  14. 28. Fusion of an egge & sperm cell
  15. 30. A single-stranded nucleic acid that passes along genetic messages
  16. 32. A change in a gene or chromosome
  17. 33. Sequence of DNA that codes for a protein
  18. 35. 3 adjacent bases on a stand of DNA or RNA that provides genetic code information for a particular amino acid
  19. 36. Process by which a gene produces its product & the product carries out its funtion
  20. 37. Enzyme that links together the growing chain of RNA nucleotides during transcription using DNA as a template
  21. 39. Virus that infects bacteria
  22. 40. Combining gametes from parents with different traits (creates hybrids)
  23. 41. A scientist separates a developing embryo to form 2 independent clones
  24. 42. Sequence of DNA that is not involved in coding for a protein
Down
  1. 1. Humans choose the traits that they prefer in their plants & animals & only allow those to reproduce
  2. 2. The study of heredity
  3. 4. Process by which mRNA is decoded and a protein is produced
  4. 5. Mendels 2nd conclusion, which states that some alleles are dominant and some are recessive
  5. 6. A segment of DNA on a chromosome that codes for a specific trait
  6. 9. Synthesis of an RNA molecule from a DNA template
  7. 10. An organism that has 2 identical alleles for a trait (BB, bb)
  8. 12. Enzyme responsible for joining individual nucleotides to produce DNA molecules
  9. 13. A chain of amino acids linked together by peptide bonds
  10. 14. Unique sequence of DNA base pairs that can be used to identify a person at the molecular level
  11. 17. Different forms of a gene (blue eyes, brown eyes...)
  12. 24. Copying process by which a cell duplicates its DNA
  13. 25. The direct manipulation of genes for a practical purpose
  14. 26. Genetically Modified Organism
  15. 29. A characteristic that an organism can pass on to its offspring through its genes
  16. 31. RNA molecule that transfers amino acids to ribosomes during protein synthesis
  17. 34. RNA that carries copies of instructions for the assembly of amino acids into proteins from DNA to the rest of the cell
  18. 38. Ordering of nucleotides in DNA molecules that carries the genetic information in living cells
