Genetic Recombination
Recombination is crucial to this process because it allows genes to be reassorted into diverse combinations. Genetic recombination is the process of combining genetic components from two different origins into a single unit. In prokaryotes, genetic recombination takes place by the unilateral transfer of deoxyribonucleic acid. It includes transduction, transformation, and conjugation. The genetic exchange occurring between homologous deoxyribonucleic acid sequences (DNA) from two different sources is termed general recombination. For this to happen, an identical sequence of the two recombining molecules is required. The process of genetic exchange which occurs in eukaryotes during sexual reproduction such as meiosis is an example of this type of genetic recombination.
Microbial Genetics
Genes are the functional units of heredity. They transfer characteristic information from parents to the offspring.
Describe step 4 of recombination: Formation of a double Holliday junction
Recombination is the process of exchange of DNA material between the different organisms that result in the production of progenies with the combinations of the genetic traits that differ from the parents. In this process segments of genetic material (DNA) are broken and then recombined to create new combinations of the alleles. This process produces genetic diversity at the level of genes.
Holliday junction is a crossed shaped structure that produced during the genetic recombination. It is produced when two molecules of double stranded DNA get separated into four DNA strands in order to exchange the DNA segments that contain genetic information.
