A reciprocal exchange in which a pair of DNA with the same nucleotide sequence break and rejoin in a crossover is called __________ recombination.

Question

Quizplus · Accepted Answer

Homologous recombination involves the exchange of genetic material between two similar or identical sequences, such as two homologous chromosomes or two copies of a plasmid. This type of recombination is initiated by DNA damage or a double-strand break in the DNA, and it requires the activity of multiple proteins including RecA and Rad51. Site-specific recombination involves the exchange of DNA between two specific sites, and replicative recombination occurs during DNA replication when the replication fork encounters a lesion in the DNA. Therefore, option A is the correct choice.
