Everyone in the continental United States will have a solar eclipse on August 21, 2017. But only those within the roughly 70-mile-wide path of totality will have a shot at the most awesome celestial event one can experience: a total solar eclipse.
Recombination. Definition. noun, plural: recombinations. (1) (genetics) The process or act of exchanges of genes between chromosomes, resulting in a different genetic combination and ultimately to the formation of unique gametes with chromosomes that are different from those in parents.(2) (general) The process or act of bringing together (dissociated materials) once more.oun, plural: recombinations. (1) (genetics) The process or act of exchanges of genes between chromosomes, resulting in a different genetic combination and ultimately to the formation of unique gametes with chromosomes that are different from those in parents.
Genetic recombination is a complex process that involves alignment of two homologous DNA strands, precise breakage of each strand, equal exchange of DNA segments between the two strands, and sealing of the resultant recombined DNA molecules through the action of enzymes called ligases.hen recombination occurs during meiosis, the cell's homologous chromosomes line up extremely close to one another. Then, the DNA strand within each chromosome breaks in the exact same location, leaving two free ends.
