Study Notes
DNA Recombination
- Genetic information is exchanged through a process called DNA recombination.
- Homologous recombination occurs as a reciprocal exchange between identical or nearly identical sequences.
- Homologous recombination differs from non-homologous recombination in that it involves the exchange of genetic information between identical or nearly identical sequences.
- Inter-molecular homologous recombination occurs between two separate homologous molecules.
- The biological role of recombination is to increase genetic diversity and facilitate the repair of DNA damage.
- Non-homologous recombination occurs as a non-reciprocal exchange between different sequences with limited sequence homology, such as random insertion of viral genome.
- Inter-molecular homologous recombination is also known as inter-chromosomal recombination.
- Single-strand annealing produces a circular DNA and a linear short DNA.
- The main biological role of recombination is to increase genetic diversity and facilitate the repair of DNA damage.
- Homologous recombination occurs during meiosis, a process of cell division that produces gametes (sperm or egg cells).
