Chromosomes And Recombination Quiz

Most recombination is naturally occurring. During meiosis in eukaryotes, genetic recombination involves the pairing of homologous chromosomes. This may be followed by information transfer between the chromosomes. ... In meiosis and mitosis, recombination occurs between similar molecules of DNA . In the nucleus of each cell, the DNA molecule is packaged into thread-like structures called chromosomes
