Across
  1. 2. Circular pieces of DNA found in prokaryotes
  2. 7. A short sequence of single-stranded DNA that have base sequences complementary to the 3' end of the DNA or RNA being copied
  3. 8. In vitro method of DNA amplification
  4. 9. The process by which a cell becomes specialised into a different type of cell
  5. 11. The strand that is formed when the hydrogen bonds are broken between base pairs in DNA by DNA helicase
  6. 12. The process by which stem cells divide to make more stem cells
  7. 13. A base sequence complementary to a specific section of a gene or allele that you are trying to identify, it can be fluorescent
  8. 14. A cell that can detect a change that is causing the stimulus
  9. 22. A region of DNA that initiates the transcription of a particular gene
  10. 25. A group of enzymes that can recognise and cut specific sequences of DNA into fragments with sticky ends
  11. 28. The molecule before introns have been removed, splicing
  12. 29. When a template RNA strand is converted into a pre-mRNA strand
Down
  1. 1. A protein that binds to the promoter region of a gene
  2. 3. There is more than one codon that can code for different amino acids
  3. 4. An enzyme that fuses two fragments of DNA together
  4. 5. When two molecules can bind as they have a similar shape
  5. 6. Insert the recombinant plasmids into bacteria by this
  6. 10. An enzyme involved in transcription that builds up the phosphodiester backbone
  7. 13. When a base sequence reads the same both forwards and backwards
  8. 15. A gene that is transferred with the desired gene to enable scientists to identify which cells have been successfully altered and now contain recombinant DNA
  9. 16. When too many methyl groups attach to a gene
  10. 17. The name of the bond that holds complementary base pairs together
  11. 18. A stem cell that can differentiate into any sort of cell (found in the embryo)
  12. 19. A sequence of 3 bases that are complementary to the anticodon
  13. 20. Found in RNA and complementary to adenine
  14. 21. A technique used widely in the analysis of DNA, RNA and proteins
  15. 23. A sequence of 3 tRNA bases that are complementary to a codon
  16. 24. Drugs that work against bacteria
  17. 26. Heritable changes in gene function without changes to the base sequence of DNA caused by changes in the environment
  18. 27. A stem cell that can differentiate into any sort of cell except for the ones that make up the placenta
