3 major methods of genetic recombination
Making the world better, one answer at a time. Genetic recombination refers to the process by which two DNA molecules exchange genetic information. The three types of genetic recombination are crossing over, conservative site-specific recombination and transpositional recombination. The three ways in which genetic recombination occur in bacteria are: 1  Tranformation-bacteria are able to take up foreign DNA through their cell membranes. 2  This foreign DNA most often remains as an extrachromosomal structure called the plasmid. It occurs frequently in many different cell types, and it has important implications for genomic integrity, evolution, and human disease. Aa Aa Aa. DNA recombination involves the exchange of genetic material either between multiple chromosomes or between different regions of the same chromosome. DNA recombination involves the exchange of genetic material either between multiple chromosomes or between different regions of the same chromosome. Genetic Recombination in Bacteria. This is a process where genetic materials, contained in two separate genomes, are brought together within one unit. In bacteria the recombination takes place by (1) transformation, (2) transduction and (3) conjugation. Transduction. 1  Another method of genetic transfer and recombination is transduction. 2  This method involves the transfer of DNA from one bacterium to another with the use of a bacteriophage (phage). 3  A phage is a virus that infects bacteria. The three ways in which genetic recombination occur in bacteria are: 1  Tranformation-bacteria are able to take up foreign DNA through their cell membranes. 1 Another method of genetic transfer and recombination is transduction. 2  This method involves the transfer of DNA from one bacterium to another with the use of a bacteriophage (phage). 3  A phage is a virus that infects bacteria. 4  The phage T4 and the phage lambda, for example, both infect E. coli.
