Across
  1. 6. Is part of a transposon (two words)
  2. 7. mRNA ---> proteins
  3. 8. The __ _________ is a plasmid found in the donor cell in bacterial conjugation
  4. 10. The transfer of DNA from one cell to another by a bacteriophage.
  5. 12. Makes covalent bonds to join DNA strands: joins Okazaki fragments (two words)
  6. 13. the start codon
  7. 14. Set of “rules” that determines how a nucleotide sequence is converted into amino acid sequence of protein (two words)
  8. 20. The process of copying DNA
  9. 22. The transfer of DNA between two organisms in the same generation is known as ___________ information flow
  10. 24. Synthesizes DNA in the 5’ --> 3’ direction: proofreads and repairs DNA (two words)
  11. 26. The replacement of a single base in DNA by another base, causing a mutation; also called point mutation (two words)
  12. 27. The transfer of genetic material from one cell to another involving cell-to-cell contact; an example of horizontal information flow
  13. 29. The process of switching pieces of DNA among two sources; joining pieces of DNA from different sources
  14. 31. Structure containing DNA that physically carries hereditary information; the chromosomes contain the genes
  15. 32. Nonionizing radiation (UV light) causes the formation of _________ _________
Down
  1. 1. The transfer of bacterial chromosome fragments from one cell to another by a bacteriophage is called ____________ transduction
  2. 2. sequence of 3 bases complementary to a codon that each tRNA molecules carries and by which a tRNA recognizes an mRNA codon
  3. 3. The expressed regions of a eukaryotic gene; are separated from each other by introns.
  4. 4. Small circular piece of DNA carried by some prokaryotes; extrachromosomal
  5. 5. The genes of an organism – its’ genetic makeup; information that codes for all the particular characteristics of the organism
  6. 9. The DNA sequence that is complementary to CGAATCA
  7. 11. is antiparallel
  8. 15. RNA synthesis continues until RNA polymerase reaches this site on the DNA
  9. 16. The process by which a portion of one piece of DNA is exchanged with a portion of another piece of DNA (two words)
  10. 17. The point where DNA strands separate and new strands are synthesized (two words)
  11. 18. The transfer of genes from an organism or cell to its offspring OR the process of transcription and translation occurring within a cell (Central Dogma) is known as ___________ information flow
  12. 19. Refers to actual, expressed properties, for example a colour, an enzyme, etc
  13. 21. Redundancy of the genetic code; that is, most amino acids are encoded by several codons
  14. 23. The study of genomes
  15. 25. Recognizes specific codons and transports the required amino acids to the ribosomal translation site where they are incorporated into proteins
  16. 27. three-nucleotide sequence on mRNA that codes for a single amino acid
  17. 28. Transcription begins when RNA polymerase binds to the DNA at this site.
  18. 30. The process in which DNA is transferred from one bacterium to another as "naked" DNA in solution.
