Transcript of Unit 8 Vocabulary
Unit 8 Vocabulary1. micropipette- tool used to transfer small volumes of liquid
2. P20 micropipette- transfers 2µL - 20µL of liquid; the pipette we used for our lab
3. P200 micropipette- transfers 20µL – 200 µL of liquid
Unit 8 Vocabulary4. microliter (µL)- one millionth of a liter
5. milliliter (mL)- one thousandth of a liter
Unit 8 Vocabulary6. microcentrifuge- machine
used to spin small volumes of liquids at high speeds; must be properly balanced
Unit 8 Vocabulary7. microtube- a small plastic tube used in biotechnology that holds up to 1.5 - 2 mL
8. blank- a tube containing water used that is used to balance a microcentrifuge as needed
Unit 8 Vocabulary
9. DNA fingerprinting- using enzymes to cut up the DNA for one or more genes in a pattern that can be matched to other samples in paternity and criminal cases
Crime:
Paternity:
Unit 8 Vocabulary10. biotechnology- using biological techniques for practical applications, such as genetically modified foods
11. bioethics- the study of the moral concerns associated with biological research and applications
Unit 8 Vocabulary12. electrolysis- the breaking of
H2O into H+ and OH- using electricity
13. electrophoresis- using an electrical current to separate DNA fragments according to length
Unit 8 Vocabulary14. gel box- holds buffer and gel tray; has lid to protect user from electric current
Unit 8 Vocabulary
15. agarose gel- Jell-O-like substance poured into gel tray; acts as a filter for DNA
Unit 8 Vocabulary
16. What is the charge of DNA: positive, negative, or neutral? Negative
17. Why does the charge of DNA matter when running a gel? Since DNA is negative, it is repelled by the negative charge of the electrons flowing in the electricity, causing the DNA to move
Unit 8 Vocabulary
18. allele- a version of a gene
19. Heterozygous- 2 different alleles for a gene
20. Homozygous- a pair of the same allele for a gene
Unit 8 Vocabulary
21. restriction enzyme- cut DNA at certain sequences; used in DNA
fingerprinting; ex- HinDIII
Unit 8 Vocabulary
21. buffer- prevents large changes in
pH22. loading dye- helps DNA to sink into well; helps you to track where DNA sample is
Unit 8 Vocabulary
24. H2O- water 25. paternity- the state of being a
father

29. B+- baby’s DNA, cut
30. S0- suspect’s DNA, uncut
