What kind of interaction/bond is occurring between arginine and the glutamate?
Ionic interactions most likely; hydrogen bonds also accepted
If arginine were replaced with glutamate, give one reason as to why SPIT can no longer function.
The change results in a negatively charged R group becoming positively charged, eliminating the ionic interaction with glutamate. if the ionic interaction was important for stabilizing the shape of the protein, then the protein would be non-functional sin
What is an example of a secondary structure?
an alpha helix
How are these large green spirals held together?
Hydrogen bonds between the H on NH2 and O on C=O of the amino acids.
Propose a possible molecular reason for how the enzyme Xase would be more active in space.
Any answer that invokes environmental factors that affect protein activity or non-covalent or co
At what stage of meiosis would the amount of DNA in oocytes of this individual be equal to the amount of DNA in a liver cell in interphase before S phase
After Meiosis 1 is complete/Meiosis 2
When do sister chromatids first appear in the cell cycle?
during S phase, without considered chromosome condensation
List three reasons why there is genetic diversity in the gametes of this organism
independent assortment homologues chromosomes during meiosis
crossing over during meiosis
mutations
What would happen if the Lac repressor protein was mutated so that it could bind still lactose, but never release lactose?
The repressor could not bind DNA
Consider the HIV enzyme called reverse transcriptase. Imagine that the R groups at the active site are highly hydrophobic. In designing a drug that would bind to the active site and prevent the substrate from binding, researchers should use a molecule tha
Hydrophobic
