Answer:
The process of recombination begins with the introduction of a double strand break into one of the homologs. This has led scientists to believe that the enzymatic machinery responsible for recombination first evolved as a mechanism for the repair of dsDNA breaks
Explanation:
The enzymatic machinery is what catalyzes genetic recombination. This process exchanges genetic material between different organisms which enables to production of offspring with different combinations from those in either parents. Recombination between homologous chromosomes is usually used in DNA repair.
Answer:
➢<em>The structure of a nucleus encompasses the nuclear membrane, nucleoplasm, chromosomes, and nucleolus. The nuclear membrane is a double-layered structure that encloses the contents of the nucleus. ...
