You are a scientist, trying to work out the biological basis for learning and memory, and things havent been progressing so well lately. You decie its time to stop simply observing animals in mazes, and do some manipulitave experimentation. Luckily your lab is full of fruit flies and the lab down the hall has a source of radioactive cesium isotope that's great for inducing mutations in DNA. You can also borrow some mice from the genetic engineers and developmental biologists at the medical center. You figure you can change the genes which code for any protein that could contribute to the cellular machinery underlying learning and memory. Or you could just create random mutant strains, find mutants that affect learning and memory , and then go back to find what those mutant genes are. But first you must figure out:
At the same time another one of your grad students has generated a seperate mutant strain that he calls "Rutabaga". These flies are dumb too, but this time the student notices a decrease in neuronal cAMP levels in these flies. What protein could Rutabaga code for? How could both increasing and decreasing cAMP levels make flies less able to learn?
Is a catalase test perfromed on colonies from a BAP? State reasons to support your answer.
The enzyme hexokinase catalyzes 1st reaction in the glycolytic pathway. In the reaction, glucose is phosphorylated to form glucose-6-phosphate with ATP as phosphate donor and energy source:
When cloning a gene into an expression vector, people frequently use two different restriction enzymes so that passenger DNA can be inserted in the correct orientation with respect to promoter sequence present in the plasmid. But orientation is almos..
Determining the concentration of nacl that is isotonic for a plant parenchyma cell using 1.0 M nacl, water, test tubes in which to dilute a th nacl, using elodea leaves.
You have identified that flame wing (fw) is linked to blue eyes (be) and short legs (sl) on chromosome 2. You cross a fw, be, sl fly with flies containing various deletions within the 200 Kb.
Suppose that a series of compounds has been found in Neurospora . Compounds A-F appear to be members of an enzyme pathway.
Determine the distinguishing characteristics of lichens with regard to their nutritional needs, and what are the roles of the fungus and the alga that make up lichens?
Define anterograde axoplasmic transport. Explain why is this type of axonal transport necessary in most neurons? briefly explain molecules involved in facilitating anterograde transport.
If there was mutation in a dna triplet that changed the first triplet from ctt to ctc, would that cause the problem with the resulting polypeptide.
Early in the morning, the black caterpillars rest in a tightly packed group on the east-facing surface of the tent. In mid afternoon, the group is found on the tent under surface, each caterpillar individually hanging from the tent by just a few of i..
We have to attach all of the sources. I am having trouble finding anything but instances and biology teacher notes. I have worked on this for 2 days and only have an opening statement that seems to pretty much sum up everything.
After verifying that the protein complex was incorporated into liposomes, you put in NADH and incubate at 37°C. You are dismayed to view no color change in the pH indicator dye.
