25 Questions

1. It uncouples oxidative phosphorylation by carrying protons across the mitochondrial membrane - leading to a rapid consumption of energy without generation of ATP.

2. Recognizes and targets specific proteins to the endoplasmic reticulum in eukaryotes and the plasma membrane in prokaryotes

3. Gprotein association - exchanges GDP to GTP - converts AMP into cyclic AMP. Cyclic AMP binds to protein kinase A: Protein kinase A phosphorylates phosphorylase kinase. increases Ca which binds calmodulin proteins which then binds to phosphorylase kin

4. Irreversible reaction that require ATP first part of glycolosis

5. Dynins and kinesins (movement) - cilia and flagella

6. Unwound - participates in the active transcription of DNA to mRNA products - site of RNA Pol II regulation

7. Gene has multiple effects

8. Catalyzes the addition of bicarbonate to phosphoenolpyruvate (PEP) to form the four-carbon compound oxaloacetate

9. Do not contain F factor

10. Only one carbon center is changed

11. Isoelectric point and MW

12. PKa = pH

13. Recruits RecA protein - inhibited by LexA - results in mutagenesis

14. Enzymes in Krebs cycle that produce NADH

15. Failure of chromosome pairs to separate during meiosis

16. (His - Arg - Lys +) - (Glu - Asp -)

17. Can undergo both lytic and lysogenic cycle

18. An enzyme that removes a phosphate group from its substrate

19. Possess F factor as a plasmid independent of the bacterial genome. The F plasmid contains only F factor DNA and no DNA from the bacterial genome.

20. Tightly packed form of DNA - less accessible to protein factors that usually bind DNA

21. Phosphotransferase - is a type of enzyme that transfers phosphate groups from high-energy donor molecules - such as ATP -[2] to specific substrates. The process is referred to as phosphorylation -

22. Serine protease that cleaves on c terminal side of aromatics

23. Can result in allele differences - suce as 3:1 and 1:3

24. Measure tendency for recombination (frequency) 1cM = 1% chance of being separated

25. MRNA
