The answer would be: <span>A. Mitochondrial DNA is beneficial in both of these cases

Mitochondrial DNA or mtDNA is DNA that found in the mitochondrial. Mitochondrial DNA only inherited from mother, so it's relatively unchanged than nuclear DNA that mixed from father and mother.
Mitochondrial DNA has higher mutation rate in animals because it doesn't have repair mechanism like nuclear DNA. These mutations can be used as a clue for how close the relation of an organism to others.
This makes analyzing the ancestral relationship of organisms that closely or distantly related easier.
It’s a marine/ sea sponge it is a underwater invertebrate. It is classified as animal . Also Sea sponges do not have cell walls or chloroplast typical of plants, but contain animal cells.
Answer:
DNA is the genetic material of all the living organism except some viruses. The structure and the characteristics of the DNA was well explained by Watson and Crick.
DNA is a double stranded molecule in which nitrogenous bases are linked together. Watson and crick explained that DNA strand are antiparallel. The antiparallel nature of the strand means one DNA gas a polarity of 5' to 3' direction whereas the another strand of the DNA gas polarity of 3' to 5' direction. These two strands has opposite polarity and runs in anti parallel directions. Thus, the DNA strand known as antiparallel strands.
Answer:
