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).
Answer:
The statement is False
Explanation:
Osmotic pressure is created by the movement of water across the semi-permeable membrane. In osmosis water moves from an area which is having low solute concentration to the area which is having high solute concentration.
So in osmosis, the movement of water takes place not molecules. This pressure is caused by differences in solute concentration across the plasma membrane and water moves to high concentration to equalize the pressure. Therefore the statement is wrong.
From my knowledge and what I learned when I took biology I would say that most likely eukaryotes evolved from prokaryotes
