Answer:
Control of both RNA splicing and chromatin remodeling control of RNA splicing.
Explanation:
RNA is present as genetic material but in case of some viruses only. RNA contains the nitrogenous base ( adenine, guanine, uracil and cytosine), oxyribose sugar and phosphate group.
The bacteria do not have well developed nucleus so no chromatin remodification occurs in case of bacteria. Bacteria is devoid of introns and contains only exons in its RNA structure. The splicing process is not required in case of bacteria.
Thus, the correct answer is option (4).
It should just be the cell membrane, which regulates what comes into the cell and what leaves it.
If I understand you correctly; the two experimental treatments are the experimental condition and the control condition.
The thing differing between them should be what you want to examine, and especially the thing you want to know of how it influences something. So for example if you want to know how alcohol influences something, the difference should be that one condition will include alcohol and the other won't.
The answer would be 4. The shapes that are filled in half are the carriers, the one fully filled in have the condition and the ones that are white are not carriers/dont have condition.
Hoped this helped :)
