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: Strand displacement and annealing
Deoxyribonucleic acid or DNA is a molecule that contains the genetic code of the organisms. DNA cloning is the recombinant DNA technology that uses the principle of ‘cut and paste’ mechanism of molecular cloning mechanism. Cloning is a technique that produces many identical copies of DNA. DNA cloning refers to the replication of a single DNA molecule starting from a single living cell to generate a large population of cells containing identical DNA molecules. It is thus referred to as “manipulation of genes”. Gene cloning involves using a bacteria to make the multiple copies of genes with the help of cloning vectors. DNA clones are used to find genes, map genes and transfer them between species. Cloning technology is used to find carriers of genetic disorders, perform gene therapy, and create disease-resistant plants.
