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.
What are the steps of recombination?
The physical crossing over during meiosis of parental heterozygous homologous chromosomes or genes are broken and pieces and recombined into the new combinations is called recombination. The amount of crossing-over that will happen depends upon the distance between the two genes on the chromosome. The genes that are present closer together are less likely to undergo crossing over. This recombination process creates genetic diversity at the gene or DNA sequence level in an organism.
