Study Notes
Recombination of DNA: Types and Examples
- Gene C is now located on the same chromosome as genes D and E
- Two types of recombination: Homologous recombination and nonhomologous recombination
- Site-specific recombination occurs between particular short sequences present on dissimilar parental molecules
- Site-specific recombination requires specific enzymatic machinery for each particular site
- Replicative recombination generates a new copy of a DNA segment
- Recombination can be detected using the Recombination Detection Program (RDP)
- Advantages of genetic recombination include DNA homogenization, new allele combinations, and separation of alleles over time
- Disadvantages of genetic recombination include separation of advantageous traits and important gene combinations in offspring
- Recombination allows nonfunctional alleles to be cleared from a population and rare beneficial alleles to be tested
- Without recombination, a deleterious mutant allele would cause an entire chromosome to be eliminated from the population
- Recombinational events can be detected in natural populations, such as a recombinant dengue virus type 1 with three recombination regions in Guangdong province, China
- Replicative recombination is catalyzed by a specific enzyme that recognizes a short sequence present in the target site in the bacterial chromosome.
