Explanation:
Answer:
b) an ancestral cell most likely engulfed and aerobic prokaryote in a relationship that proved beneficial for both cells
Explanation:
The evolution of mitochondria occurred when a prokaryotic ancestral cell engulfed an aerobic prokaryote. This aerobic prokaryote had the ability to perform aerobic respiration. The symbiont was sustained in the ancestral cell as the association was beneficial to both of them. The ancestral cell could drive a large number of ATP by aerobic respiration.
Gradually, symbiont lost the ability of free survival and led to the evolution of mitochondria. The presence of circular DNA and ribosomes in mitochondria similar to the prokaryotic cells prove their origin by endosymbiosis.
Because it makes accessing them easier for the cell, it is assumed that the bases will be on the outside of the DNA molecule.

What is DNA molecule?</h3>
- Because the two DNA strands are made up of simpler monomeric units termed nucleotides, they are referred to as polynucleotides.
- Each nucleotide is made up of a phosphate group, a deoxyribose sugar, and one of the four nitrogen-containing nucleobases (cytosine [C], guanine [G], adenine [A], or thymine [T]).
- An alternating sugar-phosphate backbone is created when the nucleotides are linked together in a chain by covalent connections (also referred to as the phospho-diester linkage) between the sugar of one nucleotide and the phosphate of the next.
- To create double-stranded DNA, the nitrogenous bases of the two distinct polynucleotide strands are joined by hydrogen bonds in accordance with the base pairing principles (A with T and C with G). Pyrimidines and purines make up the two families of complimentary nitrogenous bases.
