Seamount and guyot are types of mountain - so we can reject those options, since we're looking for a flat surface, not a mountain.
A trench is a narrow ditch, or depression so also it's not a plain
The correct answer is abyssal plain - it's a plain typically next to a continental rise (leading to the continent) and a mid-ocean ridge.
The correct answer is: In DNA and RNA, a phosphodiester linkage connects the 3' carbon of one nucleotide and the 5' carbon of another.
The phosphate of one nucleotide is covalently bound to the sugar of the next nucleotide in DNA molecule (or hydroxyl groups in phosphoric acid react with hydroxyl groups on 3' carbon atom of one sugar molecule (deoxyribose) and the 5' carbon atom of another sugar molecule (deoxyribose) to form two ester bonds). In RNA molecule linkage is between the 3' carbon atom of one sugar molecule (ribose) and the 5' carbon atom of another, (ribose).
Hydrolysis of phosphodiester bonds is catalyzed by the action of enzymes phosphodiesterases.
