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