Lab Instruments
Timmy wants to view smaller parts of his sample, so he puts a small droplet on a slide, and views it using what instrument?
Microscope
Tom and Jerry are studying for an upcoming biology exam on photosynthesis. Tom says, "Photosynthesis uses light energy to produced ATP and NADPH"
Jerry says, "You're wrong!!! Photosynthesis produces ATP only!"
Who is right?
Tom is right, Jerry is gonna flunk his exam
Harry has a sample containing DNA fragments of varying sizes. He wants to separate them somehow. What technique could he use?
Gel electrophoresis
Gregory is studying about an animal that can survive for decades without food, entering a state where its metabolism nearly stops. What is this animal?
Tardigrade
Billy wants to pipette 21 uL (microliters) of buffer into a microcentrifuge tube. Which pipette would he use:
P2, P20, P200, P1000
P200
Tom and Terry are studying for an upcoming MCDB 108B biochemistry quiz. They are both unsure of what products are made in glycolysis. Can you help them? (2 answers are ok!)
2 ATP
2 NADH
2 Pyruvate
Water
Ron has just read about a cool gene-editing tool that uses a guide RNA to direct a nuclease to a precise genomic location. What is this called?
CRISPR-Cas9
Rowley is reading an interesting article about Antartic fish that produce a type of protein in their blood to prevent it from freezing in sub-zero waters. What are these proteins called?
Anti-freeze proteins
Bob has a tube of a sample he just prepared in lab, and wants to separate the individual components of the liquid sample. What machine could he use?
Centrifuge
Jimmy and Timmy are studying for another MCDB 108B quiz, but they are having trouble remembering the intermediates of the citric acid cycle. Which of the following isn't an actual intermediate?
Isocitrate, Oxaloacetate, Succinate, Isoacetate, Malate
Isoacetate
Hermoine wants to track a specific protein in a mouse she is studying. What GREEN fluorescent tag could she add to the protein to do this?
GFP
Rodrick is watching a nature documentary that talks about a type of fungus that can control the behavior of ants, making them climb plants before it kills them. What is this fungus called?
Cordyceps
Billy Bob just finished adding primers to his sample, and wants to perform PCR on them. What machine could he use to do the PCR?
Thermocycler
John and Vaughn are arguing about how much ATP is produced when 2 electrons are sent into the ETC via NADH. John thinks 5 molecules of ATP are made, while Vaughn thinks 15 molecules of ATP are made. Who is right, or, are they both wrong?
They're both wrong! 2.5 ATP are made from 2e- from NADH in the ETC. Dr. Lew would be upset...
Hagrid wants to detect specific proteins in his sample. He has already separated the proteins by SDS-PAGE and transferred them to a membrane. What would be the next step?
Hint: He uses antibodies
Western Blot
Manny is taking an ecology class, and is learning about an invertebrate that has its heart located in its head region, and a nervous system with multiple "mini-brains". What interesting animal is this?
Squid
