Protein X is a protein that is composed of four subunits of equal size--alpha, beta, delta, and gamma--that are bound by either
alexandr402 [8]

Answer:

The correct answer is e3

Explanation:

The given protein in the question proteib X contain four subunits of equal size alpha,beta,delta and gamma which are bound by either noncovalent interactions or disulfide bridges and only beta and delta subunits are bound to each other by disulfide bridges.

  As a result when the protein will undergo fragmentation it will generate 3 bands because the interaction that is present between alpha and beta subunit will break resulting in the formation of 2 bands. Now the most important fact is that the beta subunit is linked to delta subunit by di sulfide bond so when betamarcaptoethanol will act on protein X it will break the disulsulfide bond present between the beta and delta subunit to reduce both the subunit.

  Finally the interaction that is present between delta subunit and gamma subunit will be broken down to release the delta subunit which will form a single band during SDS PAGE..

Hi,

I think that you're missing some options, but here they are (let me know if I'm right!

-A population of wolves was introduced
-The amount of disease in the deer population decreased
-More grass was planted

Now, if the gene diversity decreased, it means that a lot of deer died. This could happen because wolves were introduced -this is the correct answer, and the wolves ate some deer.
