D) D, B, C, E, A, F
Explanation:
Homologous recombination (HR) is a DNA repair pathway that consists of the exchange between two identical (or very similar) DNA regions. The steps of HR are: 1-Strand exchange, which refers to the pairing between broken DNA regions; 2-Strand invasion in order to provide a DNA crossover (Holliday junction); 3- Branch migration, capable of extending the heteroduplex regions far away from DNA crossover, 4-Resolution, where Holliday junction is resolved by cleavage of the junctions; 5- In the last step, a DNA ligase enables the joining of DNA strands.
Answer:
a lunar eclipse

The shadow that Aristotle saw was caused by a lunar eclipse. At that time the sun, earth, and the moon nearly straight alignment caused the Earth's shadow to be reflected on the moon. This shadow is what ultimately led Aristotle to believe that the Earth was a sphere. This should not be confused with a solar eclipse which is similar but instead the sun, moon, and earth align in that order which causes the moon to completely block the sun to anyone on earth.
