Question 39 0.35 pts Homologous recombination is an important mechanism in which organisms use a "backup" copy of the DNA as a template to fix double-strand breaks without loss of genetic information. Which of the following is necessary for homologous recombination to occur? telomerase O 3 DNA strand overhangs • a short stretch of sequence similarity no DNA strand overhangs
