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..
The main difference is that organisms that have similar characteristics could be in the same species or have common ancestors
A procaryotic cell has five essential structural components: a nucleoid (DNA), ribosomes, cell membrane, cell wall, and some sort of surface layer, which may or may not be an inherent part of the wall.
We need carrier proteins for steroid hormones because they help in the transportation from the cell they were released from to their target cell.
