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