WebJul 19, 2024 · 8: Recombination of DNA. The chapter on mutation and repair of DNA dealt mainly with small changes in DNA sequence, usually single base pairs, resulting from errors in replication or damage to DNA. The DNA sequence of a chromosome can change in large segments as well, by the processes of recombination and transposition. Web19 hours ago · Pre-meiotic NCOGCs. There were 5 instances of NCOGCs that occurred in identical locations in different individuals from the dl-49 heterozygotes . We did not recover any similar instances in Oregon-RM.
