Homologous recombination differs from site-specific recombination in that ________.
A. homologous recombination utilizes enzymes collectively called recombinases, whereas site-specific recombination involves RecA to bring about the crossover between DNA molecules B. homologous recombination involves long stretches of similar-sequence nucleotides on two DNA molecules that break and reanneal in a crossover mechanism, whereas site-specific recombination occurs at target sites, catalazed by recombinases C. homologous recombination takes place at specific target sites catalazed by recombinases, whereas site-specific recombination involves long stretches of same-sequence nucleotides on two DNA molecules that break and reanneal in a crossover mechanism D. homologous recombination takes place in eukaryotic cells during meiosis, whereas site-specific recombination takes place in bacteria and archaea during horizontal gene transfer
