Answer:
In the 1960s, Lynn Magulis came up with the theory of endosymbiosis. Different evidence supports this theory that the cell organelles like chloroplasts and mitochondria were once utilized by the independent living species. Both of these organelles exhibit their own genetic material. The mitochondria cannot differentiate to produce chloroplasts and vice versa.
However, the fact that the mitochondria are found in all the cells of eukaryotes, while the chloroplast is witnessed only in certain specific cells, shows that the evolution of mitochondria took place much earlier than the chloroplasts.
Explanation:
Daughter cells are cells that result from the division of a single parent cell. They are produced by the division processes of mitosis and meiosis. Cell division is the reproductive mechanism whereby living organisms grow, develop, and produce offspring.
Answer:
The regularity of DNA's overall structure.
Explanation:
DNA is the genetic material of almost all the living organisms but RNA may also acts as the genetic material in some viruses only. The mutation in DNA may cause characteristic disease in individual.
The nucleotide excision repair mechanism excise the wrong nucletide and replace with the correct nucleotide. The overall DNA structure like its nucleotide sequence, the size and angles between the DNA base pair, its methylation helps in recognizing different DNA type.
Thus, the correct answer is the regularity of DNA's overall structure.

Genetic variation allows for mutations to occurs where survival of the fittest occurs. This makes sure that the most adapted creatures survive and are able to pass their genes on to offspring. Thus causing evolution.
